Do you think billionaires are a national security threat?

I have an interesting topic of a qoute from family guy There's far more money to be made in treating a disease than in curing it. Why cure someone of cancer in a day if we can treat them for a lifetime and bill 'em every step along the way?" I think politicians should tax billionaires 50% if they refuse to hand over breakthroughs like cures for diseases and new technology development to citizens while countries like China or Russia could get there hands on it which can pose a serious threat imagine if China ask Elon musk to buy his robots and stuff
