In the distribution to the public of the products of industry, the failure of the present system is the direct result of the faulty premise upon which it is based. This is: that somehow a man is able by his personal services to render to society the equivalent of what he receives, from which it follows that the distribution to each shall be in accordance with the services rendered and that those who do not work must not eat. This is what our propagandists call 'the impossibility of getting something for nothing.' Aside from the fact that only by means of the sophistries of lawyers and economists can it be explained how, on this basis, those who do nothing at all frequently receive the largest shares of the national income, the simple fact is that it is impossible for any man to contribute to the social system the physical equivalent of what it costs the system to maintain him form birth till death--and the higher the physical standard of living the greater is this discrepancy.
Here he just comes out and says it: It's ALL a free lunch.
Since also the energy-cost of maintaining a human being exceeds by a large amount his ability to repay, we can abandon the fiction that what one is to receive is in payment for what one has done, and recognize that what we are really doing is utilizing the bounty that nature has provided us. Under these circumstances we recognize that we all are getting something for nothing, and the simplest way of effecting distribution is on a basis of equality, especially so when it is considered that production can be set equal to the limit of our capacity to consume, commensurate with adequate conservation of our physical resources.
