Three corporate heirs' income could pay $333.3 mn once, which I'm assuming includes themselves. I'm not suggesting taking all their money (and they probably collectively have far more, counting hidden away assets, including liquid). So a 93% tax rate (iirc, top tier income bracket rate from the 1950s) on earnings over a couple of million per year could easily pay for basic living living, education and health? Then nationalize things required, such as health care, food, water, housing, quality (but not luxury) clothing, utilities including broadband, and of course other natural resources, nationwide and intra-Americas rail, public trolly systems, and re/build crumbling infrastructure to include massive sustainable, renewable energy, everyone could live a decent life, with adequate time for family, rest, recreation, the elite could maintain opulence and "charities," and added personal income and GDP could exponentially expand and employers would have to treat employees as human beings, rather than wage/chattel slaves, with the added bonus of not worrying about their precious, delicate necks due to civil unrest?

I obviously haven't done even the most rudimentary maths involved in this train of thought, just musing before a nap. Perhaps a math/economy pro could chime in?
