Looking at this another way: the economic decline of the middle class and the expansion of the working poor result from all these unjust deserts - all the unshared wealth that has resulted from inherited knowledge that a few people have managed to unfairly benefit from. This has produced rising economic inequality and increased economic suffering by so many Americans.
Unjust Deserts is not the easiest book to read because it is written in an academic rather than a populist style. Nevertheless, for anyone who wants better justification for “taxing the rich” public policies it is essential reading. Another good title for the book would have been: Battling Economic Injustice.
