I don’t like the idea of a maximum wage. Not for working class anyway. I have seen too many people refusing to work overtime because the tax rates are too high. This ensures they’ll never get ahead. On the other hand I don’t think anyone earning minimum wage should pay a dime in income taxes.
The solution for billionaires is simple. Abolish income tax and tax the living shit out of capital gains and inheritances. The can hoard as much wealth as they want but when the reaper comes to call the government gets most of it.
