First, thanks for a serious Response.

The "allotted income" would not depend in any way on the generation of income through the production of goods and services, so it would be completely independent of that process, however it might proceed. The amount of the income would not be affected by changes in total income.

As long as everyone has enough for a sufficient level of material well-being (a solidly ‘middle class’ life in a so-called ‘first world’ nation) does it matter how much more some may have? In my understanding of justice no such differences are of themselves unjust.

One option, just mentioned in that article, would be to extend that income to be the pay of all employees of any business or government, which would address exploitation. It would also maximize sustainability. That option (which I favor) is more fully developed in "To Preserve What We Have, What We Have Must Be Enough."
