We already essentially have a tiny bit of that in the form of the capital gains tax. Raise that a bit to fund public sector investment (but maybe not now because interest rates on borrowing are so low) and set a steep inheritance tax and you've gotten much closer. As for distribution of the money afterwards, doing everything at the federal level isn't desirable for a lot of things, so transfer that to state and local governments in those cases. Although a prerequisite to any of this being a good idea is making our democracy a lot more functional.
