The effective tax rate for the top 1% is within 3% of the top effective tax rate that they've ever paid historically, FYI.
The rich pay almost as much in taxes as they ever have, and yet people are stupid enough to think that they aren't paying anything.
The only real tax loophole that is preventing some very wealthy people from paying a lot in taxes is carried interest, and that only applies to a minority of workers in private equity funds.
