The top tax rate bracket in the US was over 90% from 1944-1963. A median single income worker could own a home, have healthcare, food, and afford kids. GDP was doing just fine, I assume that's what you mean by revenue.
The top tax rate now is 37%, and a median single income earner can sometimes afford a 1 bedroom without relying on a 2nd set of income. Can't afford buying a home. Food scarcity is getting worse. Healthcare is fucked beyond belief. And kids are just flat out of the question.
As a country we aren't getting our fair share of the value of our labor. Ideally the benevolent job creators would create good paying jobs, and make the middle class stop struggling. When this doesn't happen, we need to give them an incentive. I'm not saying we should increase taxes, unless there is no other option.
What ideas besides taxes do you have to make the billionaire class give us a minimum standard of living that isn't dystopian?
