I can't wait for the "we had a 90% rate before" argument... all the while failing to remember the deduction rules were MUCH different at that time, wherein the effective rate was still less than 50% (and if I remember correctly, just about where they are now)
The effective rate is around 20% or slightly less now, overall.
The effective rate was of course less than the top marginal rate, always is, but the marginal tax rate on dollars earned over a couple million (in todays dollars) was closer to the top rate.
