There are some tax writing experts on the Hill who can figure out how to do that of course, but think of the advantage ~ Republicans don't pay more taxes, yet Democrats get the tax increase they want.
The parameters of the tax are it has to take all their accumulated wealth as well as current income. In the end they go bankrupt and have to move out into the streets to live under wool blankets held up by cardboard boxes.
Their chilun' are seized by Child Protective Services and sent to government orphanages.
They automatically get a felony conviction put on their criminal record and they lose their credit ratings.
It's only fair!
