Corporate taxes used to cover over 30% of government revenue, it's 10% now. The top marginal income tax rate peaked in the 1960s at somewhere around 80% on income exceeding ~3M/year (today's money). We've had 4 decades of tax cuts while the cost of delivering services has increased more or less with the inflation rate. Private equity funds now have favourable tax treatment, and stock buybacks, previously considered illegal stock manipulation is a common practice. And so on and so forth.
If you want what you had, you have to do what you did.
