So, if I invent a cure for cancer, or a cheap, abundant, pollution-free source of energy, or a cybernetic exosuit so Stephen Hawking can fight crime, I should just give it away, because if I try to profit from my ingenuity I'll be effectively bankrupt? An 80% tax rate on high earners has worked fine in history, a 110% rate basically says if you're the next Bill Gates or Jeff Bezos you're screwed.
In any case, my point wasn't "my teacher believed wacky things I disagree with", it was "my teacher didn't like me disagreeing with him, and I strongly suspect my final grade suffered as a result, as much of the final was subjective"
