The marginal tax rate was
91% under Ike starting at $400,000
70% from Nixon to Carter, at $200,000
28% under Reagan at $300,000.
40% under Clinton at $288,000. Which became 35%, under the famous Bush tax cuts.
(remind me why we can't afford social security!)
If you were an AIG trader collecting $6 million in 2004 after taking a risk which might -and did- bankrupt your employer you'd have kept $3,900,000 to comfort you if your social security was inadequate.
