No. I would support the ending of all tax shelters like the creation of “foundations” and fake non-profits used to enrich these kinds of people and allow them to retain use of the money while avoiding taxes. I would also support a true alternative minimum tax for very high income people such that their marginal tax is a true 35% without any deductions allowed for income about 5m/yr. I do not support any kind of wealth tax. I would prefer a consumption tax to replace the income tax.
The tax shelters exist because the wealthy bribed Congress to create them.
There is no way to get that toothpaste back in the tube (imho).
Term limits could give you a Congress that _might_ be willing to seriously address the issue, but in the real world Congress-critters are commodities for the rich, bought and sold like toilet paper.
