"Redistribution" doesn't mean you take rich people's money in a one-off scheme. It means that you tax them higher. One particular opportunity there is capital gains tax, which has been much lower than sweat-of-the-brow income for a long time now. Equalize the rates (or better yet, jack capital gains up even higher - there's no reason to encourage economic rent over labor), and you've got a very nice monetary stream to direct elsewhere.
