That has just triggered a thought.
The ultra-rich should face ultra-high taxation rates UNLESS their surplus wealth is re-invested in American based companies, manufacturing goods that are at least 75% made in America, not merely made elsewhere and then given a token makeover.
It would solve trade imbalance problems with China, etc. and make the ultra rich contribute far more heavily to raising up the people who made them rich - with the enticing prospect of becoming even richer in the long term.
How's that for an election policy?

And if inflation were factored in this would wipe out middle-class gains and put the poorest in the negative.

It's a horrifying inditement of capitalism as practised in America.
There's also an unconsidered spin-off from this. Manufacturers create luxury goods, with a truly excessive profit margin, knowing that the ultra rich will vie with each other to have the latest fad, and this has a trickle down effect to the next lower level of society, and creates a thriving second-hand market for their used products. (Think Apple, luxury cars and exotic brand names, most of which are produced in far Eastern countries like China with atrociously low wages.) Meanwhile serviceable, reliable products are no longer massively produced in the USA, because they are not "high margin" products. Previously, such products were still worth making for reasons of sheer sales volume (1 million items at 1 dollar profit each puts 1 million dollars in the bank)

It is disgusting how the rich have gotten so rich at the expense of the poor and middle class.
