I think personal income should be taxed at 100% over, let's say, a hundred grand. No one needs or deserves to be rich. The wealthy have a hoarding disorder and they give us nothing but social inequality. Surplus income is put to better use in education, infrastructure, health care, and scientific research. On this point my conscience doesn't feel queasy one little bit.
Taking that much capital out of the private sector to finance government run business is Socialism. I don't think we're ready for that yet.
Who´s "we"?We may have the exterminate half of humanity to save the other half of humanity.
