Wow, that chart shows tax rates on the wealthy dropping from 70% to 23% in the last 70 years. Now probably 70% was too socialist and may not fly in a globalised world where is a lot easier to move to a lower tax country or state (I'd move if I had to pay that.) But this seems ridiculously tilted to the other extreme now.
Edit: I don't understand the objections to my comment. If you have a problem with the data behind that chart, that's not my problem.
If you object to the usage of the word socialist - that's a common usage, don't be so pedantic.
