Even beyond this, I see little proof that individuals having absurd amounts of money is in any way beneficial to society, at least on any consistent basis.
To be perfectly honest, I almost feel that there should be a legislated maximum income disparity within a company to reduce the insanity that can happen. Maybe something like no employee may make more than 100 times what another employee makes in terms of net hourly compensation. 100 times is still an absolutely massive disparity, and yet this would improve things. Want to pay your CEO more? Give your janitors a raise.
