90% of the population might agree with that idea.
but the billionaires just need less than 1% to disagree: the people which run the country.
At the risk of sounding like a socialist, billionaires didn't just get that way. They either stole, inherited, or gut rich on the backs of many hard working people. With about three exceptions, you know who they are, ALL are self-serving greedy pricks. Leave them with enough so that they can feed themselves (a few million) and use the rest to improve the lives of everyone else on the planet Earth.
never happen. unless times become truly apocalyptic & by then their money won't matter.
but the homeless could improve their accomodation after the billionaires flee to their huge estates guarded by private armies in patagonia.
