Scroll down to the bottom of that page to the "Income tax rates in history" section. Observe that the top marginal rate was as high as 91%, and did not drop below 80% in the entire period between 1936 and 1981.
I know what it was but that wasn’t ever in reality actually the case almost no one paid the exesses taxes during, heck forget almost no one paid that marginal rate.
That's true, because almost no one made enough money to pay it. That's one of the reasons that it wasn't harmful.
> So you want 91% tax from what amount?
I dunno, $5-10M or so. I also think that you should be able to defer the recognition of income so that you don't get dinged too heavily for one-time windfalls. But I think anyone regularly making $5-10M/yr should be paying a lot more than they currently do.
