They wouldn't, under any circumstance.I believe that a sale tax system would work better. The wealthy buy a lot of expensive homes, cars, yachts, jewelry, planes, cloths, paintings, race horses, eat at expensive restaurants, take expensive vacations, and spoil their children
The ultra wealthy pretty much control the tax code with their campaign brib, I mean contributions.
SO why would the ultra wealthy support the tax code as you just defined it? They have worked hard and spent plenty to have the tax code that we currently use. Why would they support a big change like you propose?
Then why do people like you constantly trot out this fantasy taxation dream? Just the idea that us middle class folk are going to be able to bring about a major, drastic tax system change that the ultra wealthy do not support is quite simply, laughable.
