The great thing about many religous "gurus" is their ability to explain common sense in the form of simple stories or parables. 

Thanks to Sameer Panje I came across this article by Ambedkar on the Buddha. I'll talk more about the article later, but for now I'm extracting a nice little story about why a social minimum is needed. This is a strategic argument. There are, of course, many other arguments (see DOF). But this is perhaps one of the most important.

In a sermon addressed to the Bhikkus the Buddha has shown the difference between the rule by Righteousness and Rule by law i.e. force. Addressing the Brethren he said:

(2) Long ago, brethren, there was Sovereign overlord named Strongtyre, a king ruling in righteousness, lord of the four quarters of the earth, conqueror, the protector of his people. He was the possessor of the celestial wheel. He lived in supremacy over this earth to its ocean bounds, having conquered it, not by the courage, by the sword, but by righteousness.

(3) Now, brethren, after many years, after many hundred years. after manu thousand years, king Strongtyre command a certain man, saying:

"Thou should est see, Sir, the Celestial Wheel has sunk a little, has slipped down from its place, bring me word. "

Now after many many hundred years had slipped down from its place On seeing this he went to King Strongtyre and said: "Know. sir, for a truth that the Celestial Wheel has sunk, has slipped down from its place. "

The king Strongtyre, brethren, let the prince his eldest son be sent for and speak thus:

' Behold, dear boy, my Celestial Wheel has sunk a little, has slipped down from its place. Now it has been told me; If the Celestial Wheel of a wheel turning King shall sink down, shall slip down from its place, that king has not much longer to live. I have had my fill of human pleasures; 'It's time to seek after divine joys, Come, dear boy, take thou charge over this earth bounded by the ocean. But I, shaving, hair and beard, and donning yellow robes, will go forth from home into the homeless state.

So brethren. King Strongtyre, having in due form established his eldest son on the throne, shaved hair and bearded, donned yellow robes and went forth from home into homeless state. But on the seventh day after the royal hermit had gone forth, the Celestial Wheel disappeared.

(4) Then a certain man went to the King, and told him, saying: Know, 0 King, for a truth, that the Celestial Wheel has disappeared!

Then that King, brethren, was grieved thereat and afflicted with sorrow. And he went to the royal hermit, and told him, saying, Know, sir, for a truth, that the Celestial Wheel has disappeared.

And the anointed king so saying, the royal hermit made reply. Grieve thou not, dear son, that the Celestial Wheel has disappeared, nor be afflicted that the Celestial Wheel has disappeared. For no paternal heritage of thin, dear son, is the Celestial Wheel. But verily, dear son, turn thou in the Ariyan turning of the Wheel-turners. (Act up to the noble ideal of duty set before themselves by the true sovereigns of the world). Then it may well be that if thou carry out the Ariyan duty of a Wheel-turning Monarch, and on the feast of the moon thou wilt for, with bathed head to keep the feast on the chief upper terrace, to the Celestial Wheel will manifest, itself with its thousand spokes its tyre, navel and all its part complete. (5) 'Put what, sire is this Ariya duty of a Wheel-turning Monarch?' This, dear son, that thou, leaning on the Norm (the law of truth and righteousness) honouring, respecting and revering it, doing homage to it, hallowing it, being thyself a Norm-banner, a Norm-signal, having the Norm as thy master, should provide the right watch, ward, and protection for thine own folk, for the army, for the nobles, for vassals, for brahmins and house holders, for town and country dwellers, for the religious world, and for beasts and birds. Throughout thy kingdom let no wrongdoing prevail. And whosoever in thy kingdom is poor, to him let wealth be given.

' And when dear son, in thy kingdom men of religious life, renouncing the carelessness arising from intoxication of the senses, and devoted to forbearance and sympathy, each mastering self, each claiming self, each protecting self, shall come to thee from time to time, and question the concerning what is good and what is bad. what is criminal and what is not, what is to be done and what is to be left undone, what line of action will in the long run work for weal or for woe, thou shouldest hear what they have to say and thou shouldest deter them from evil, and bid them take up what is good. This, dear son, is the Ariyan duty of a sovereign of the world.'

' Even so, ' sire, answered the anointed king, and obeying, and carried out the Ariyan duty of a sovereign lord. To him, thus behaving, when on the feast of the full moon he had gone in the observance with bathed head to the chief upper Terrance the Celestial Wheel revealed itself, with its thousand spokes, its tyre. its naval, and all its part complete. And seeing this is occurred to the king: ' It has been told me that a king to whom on such a occasion the Celestial Wheel reveals itself completely, becomes a Wheel-turning monarch. May I even I also become a sovereign of the world.'

(6) Then brethren, the king arose from his seat and uncovering his robe from one shoulder, took in his left hand a pitcher, and with his right hand sprinkled up over the Celestial Wheel, saying: ' Roll onward, O Lord Wheel! Go forth and overcome, O Lord Wheel ! ' Then, brethren, the Celestial Wheel rolled onwards towards the region of the East. and after it went the Wheel-turning king, and with him his army, horses and chariots and elephants and men. And in whatever place, brethren, the wheel stopped, there the king, the victorious war-lord, took up his abode, and with him his fourfold army. Then the all, the rival kings in the region of the East came to the sovereign king and said 'Come, O mighty king! Welcome, O mighty king! All is thine, O mighty King! Teach us, O mighty king! '

The king, the sovereign war-lord, speak thus: 'Ye shall slay no living thing. Ye shall not take that which has not been given. Ye shall not act wrongly touching bodily desires. Ye shall speak no lie. Ye shall drink no maddening drink. Enjoy your possessions as you have been wont to do.'

(7) Then, brethern, the Celestial Wheel, plunging down to the Eastern ocean, rose up out again, and rolled onwards to the region of the south…. (and there all happened as had happened in the East). And in like manner the Celestial Wheel, plunging into Southern ocean, rose up out again and rolled onward to the region of the West. . . and of the North: and there too happened as had happened in the Southern and West.

Then when the Celestial Wheel had gone forth conquering over the whole earth to its ocean boundary, it returned to the royal city, and stood, so that one might think it fixed, in front of the judgement hall at entrance to the inner apartments of the king, the Wheel-turner, lighting up with its glory the facade of the inner apartments of the king, the sovereign of the world.

(8) And a second king. brethern, also a Wheel-turning monarch,. . . and a third. . . and a fourth. . . and a fifth. . . and a sixth. . . and a seventh king, a victorious war-lord, after many years, after many        hundred years, after many thousand years, command a certain man, saying:

'If thou should'est see, sirrah, that the Celestial Wheel has sunk down, has slid from its place, bring me word.' 'Even so, sire.' replied the man.

So after many years, after many hundred years, after many thousand years, that man saw that the Celestial Wheel had sunk down, had become dislodged from its place. And so seeing he went to the king, the warlord, and told him.

Then that king did (even as Strongtyre had done). And on the seventh day after the royal hermit had gone forth the Celestial Wheel disappeared.

Then a certain man went and told the King. Then the King was grieved at the disappearance of the wheel, and afflicted with grief. But        he did not go to the hermit-king to ask concerning, the Ariyan Duty of sovereign war-lord. But his own ideas, forsooth, he governed his people; and they so governed differently from what they had been. did not prosper as they used to do under former kings who had carried out the Arivan duty of a sovereign king.

Then, brethren, the ministers and courtiers, the finance officials, the guards and door keepers and they who lived by sacred verses came to the King and speak thus:

'Thy people, O king. whilst thou governest them by thine own ideas differently from the way to which they were used when former kings were carrying out the Arivan Duty prosper not. Now there are in thy kingdom ministers and courtiers, finance officers, guards and custodians, and they who live by sacred verses—both all of us and others—who keep the knowledge of the Ariyan duty of the sovereign king. to ! O king. do thou ask us concerning it: to thee thus asking will we declare it.'

9. Then, brethren, the king, having made the ministers and all the rest sit down together, asked them about the Ariyan duty of Sovereign war-lord. And they declared it unto him. And when he had heard them, he did provide the due watch and ward protection, but on the destitute he bestowed no wealth and because this was not done, poverty became widespread.

When poverty was thus become rife, a certain man took that which others had not given him, what people call by theft. Him they caught, and brought before the king, saying: 'This man, O king has taken that which was not given to him and that is theft'.

Thereupon the king speak thus to the man. 'Is it true sirrah, that thou hast taken what no man gave thee, hast committed what men call theft.' It is true, O king.' 'But why?'

'O king, I have nothing to keep me alive.' Then the king bestowed wealth on that man, saying: 'With this wealth sir, do thou both keep thyself alive, maintain thy parents, maintain children and wife, carry on thy business.' 'Even so, O king,' replied the man.

10. Now another man, brethren, took by theft what was not given him. Him they caught and brought before the king and told him., saying: 'this man, O king, hath taken by theft what was not given him'.

And the king (spoke and did even as he had spoken and done to the former man.)

II. Now men heard brethren, that to them who had taken by theft what was not given them, the King was giving wealth. And hearing they thought, let us then take by theft what has not been given us.

Now a certain man did so. And him they caught and charged before the king who (as before) asked him why he had stolen. 'Because, O king I cannot maintain myself. Then the king thought: If I bestow wealth on anyone so ever who has taken by theft what was not given him, there will be hereby and increase of this stealing. Let me now put final stop to this and inflict condign punishment on him, have his head cut off!

So he bade his man saying ' now look ye! bind this man's arms behind him with a strong rope and tight knot, shave his head bald, lead him around with a harsh sounding drum, from road to road, from cross ways to cross ways, take him out by the southern gate and to the south of the town, put a final stop to this, inflict on him uttermost penalty, cut of his head.'

' Even so, O king ' answered the men, and carried out his commands.

12. Now men heard, brethren, that they who took by theft what was not given them were thus put to death. And hearing they thought, let us also now have sharp swords made ready for themselves, and them from whom we take what is not given us—what they call them— let us put a final stop to them, inflict on them uttermost penalty., and their heads off.

And they got themselves sharp swords, and came forth to sack village and town and city, and to work highway robbery. And then whom they robbed they made an end of, cutting off their heads.

13. Thus, brethren, from goods not being bestowed on the destitute poverty grieve rife; from poverty growing rife stealing increased, from the spread of stealing violence grew space, from the growth of violence the destruction of life common, from the frequency of murder both the span of life in those beings and their comeliness also (diminished).

Now among humans of latter span of life, brethren, a certain took by theft what was not given him and even as those others was accused before the king and questioned if it was true that he had stolen. 'Nay, O king,' he replied, 'they are deliberately telling lies.' 14. Thus from goods not being bestowed on the destitute, poverty grew rife… stealing… violence… murder… until lying grew common.

Again a certain man reported to the king, saying ' such and such a man, O king! has taken by theft what was not given him '— thus speaking evil of him.

15. And so, brethren, from goods not being bestowed on the destitute poverty grew rife… stealing… violence… murder… lying… evil speaking grew abundant.

16. From lying there grew adultery.

17. Thus from goods not being bestowed on the destitute, poverty…   stealing…   violence…   murder…   lying…   evil speaking. . . immorality grew rife.

18. Among (them) brethren, three things grew space incest, wanton greed and perverted lust.

Then these things grew apace lack of filial piety to mother and father, lack of religious piety to holy men, lack of regard for the head of the clan.

19. There will come a time, brethren, when the descendants of those humans will have a life-span of ten years. Among humans of this life span, maidens of five years will be of a marriageable age. Among such humans these kinds of tastes (savours) will disappear; ghee, butter, oil of tila, sugar, salt. Among such humans kudrusa grain will be the highest kind of food. Even as to-day rice and curry is the highest kind of food, so will kudrusa grain will be then. Among such humans the ten moral courses of conduct will altogether disappear, the tenimmoral courses of action will flourish excessively; there will be no word for moral among such humans, the ten moral courses of conduct will altogether disappear, the ten immoral courses of action will flourish excessively, there will be no word for moral among such humans—far less any moral agent. Among such humans, brethren, they who lack filian and religious piety, and show no respect for the Head of the clan—'tis they to whom homage and praise will be given, just as to-day homage and praise are given to the filial minded, to the pious and to them who respect the heads of their clans.

20. Among such humans, brethren, there will be no (such thoughts of reverence as are a bar to intermarriage with) mother, or mother's sister, or mother's sister-in-law, or teacher's wife, or father's sister-in-law. The world will fall into promiscuity, like goats and sheep, fowls and swine, dogs and jackals.

Among such humans, brethren keen mutual enmity will become the rule, keen ill-will, keen animosity, passionate thoughts even of killing, in a mother towards her child, in a child towards its father, in brother to brother, in brother to sister, in sister to brother. Just a sportsman feels towards the game that he sees, so will they feel.
