The author misses the entire point of a capitalist economic system, as does the Commie professor who created this bu!!$hit game. Wealth isn't earned, it's created. If we assume that it's earned, we assume that there's only so much available to be earned. A capitalist economy creates wealth, allows all who wish to participate to be a part of that wealth creation, and share the rewards in proportion to the value they add.
Duh.
