“A global super-rich elite had at least $21 trillion (£13tn) hidden in secret tax havens by the end of 2010, according to a major study.”
They’re hiding it, so it must be ill-gotten, and therefore unearned. Since they didn’t earn it, it’s not legitimately theirs. It may be seized by the IRS and (after keeping some to fund the operations of the IRS) redistributed to the People’s Liberation Army through interest payments, just like everyone else’s taxes.
The catch is it isn’t easy to get hold of this money. Most of it is in accounts owned by cronies of powerful politicians, who have written the laws so that the money in a finicky legalistic technical sense, actually belongs to that global super-rich elite. It seems like the easiest way to take it back for the people is to inflate the currency. Which to the government’s credit they have been trying to do.
