A few problems there though. 1. Sure tax rates were as highly as 90% under Ike, but no one actually paid that, or even close to it. That is because almost everything was a deduction.
2. Democrats like to lump in the working wealthy with the likes of the corporate raiders and hedge fund managers. Attacks on the bullshit tax treatment carried interest, regulated futures, and inversions offshore I can dig. Attacks on the PH.D. Making $300K a year I cannot.
