Somewhere along the way, in the U.S. and the U.K the point of society became seeing how rich some individuals could get. Anything that could be perceived as getting in the way of that became 'bad'.

I recommend two things. First, eliminate bonuses (money, stocks, or any other financial instrument) as a form of compensation. There would be no limit on income, but it would have to be regularly scheduled. It is bonuses, especially using stocks, have created billionaires. Essentially, that is corporations printing money to give to senior executives. Second, impose a maximum ratio for the total remuneration (money and benefits) of the highest-compensated person and the lowest-compensated person in any organization with at least one employee. Say, 20:1?That would not put a limit on income, either.
