Labor is required by nature, not by capitalism.
I quote Frédéric Bastiat:
Man recoils from trouble, from suffering; and yet he is condemned by nature to the suffering of privation, if he does not take the trouble to work. He has to choose, then, between these two evils. What means can he adopt to avoid both? There remains now, and there will remain, only one way, which is, to enjoy the labor of others. Such a course of conduct prevents the trouble and the satisfaction from preserving their natural proportion, and causes all the trouble to become the lot of one set of persons, and all the satisfaction that of another. This is the origin of slavery and of plunder, whatever its form may be - whether that of wars, imposition, violence, restrictions, frauds, etc. - monstrous abuses, but consistent with the thought which has given them birth. Oppressors should be detested and resisted - they can hardly be called absurd.
Slavery is disappearing, thank heaven! and, on the other hand, our disposition to defend our property prevents direct and open plunder from being easy.
One thing, however, remains - it is the original inclination which exists in all men to divide the lot of life into two parts, throwing the trouble upon others, and keeping the satisfaction for themselves. It remains to be shown under what new form this sad tendency is manifesting itself.
The oppressor no longer acts directly and with his own powers upon his victim. No, our conscience has become too sensitive for that. The tyrant and his victim are still present, but there is an intermediate person between them, which is the State - that is, the Law itself.
