Jonathan Chait says that Jeb Bush's newly-released plan for the American economy is basically his brother's "tax cuts for the rich" idea dressed up with a few token, minor tax hikes for some rich folks and a few token, minor tax cuts for the non-rich. One nice thing about Donald Trump is that he's a Republican who's at least open to the idea that cutting taxes for wealthy folks does not automatically grow the economy enough to make up for those lost revenues. If you're any other Republican seeking public office, you're forbidden to even consider that might not work, no matter how many times it fails to work.
