One thing missing from the discussion so far is the point that a 70 percent top tax rate exists, not merely in midcentury US tax codes or in academic papers, but also in the real world right now. Sweden has a 70 percent marginal tax rate and it kicks in, not at $10 million like AOC proposes, but at around $98,000. AOC’s proposal is quite modest by comparison.
According to the OECD, single Swedish workers making over 867,000 SEK (around $98,000 at prevailing exchange rates) face a 70 percent overall marginal tax rate on all labor compensation earned above that threshold. The below graph decomposes this overall marginal rate into its three parts and shows how much is left for take home pay:
Where do Swedish earnings over $98,000 go?
21.5% Central Income tax
24.7% Local Income tax
23.9% Payroll tax
Leaving about 30% take home pay

I bet the tax system encourages people to aim for a lower salary were the high taxes don't kick in. Instead of $98K they might shoot for $50K.
