Billionaires are gross, millionaires are fine. You're committing the "slippery slope" fallacy in defense of excessive wealth inequality. (And if you genuinely believe what you're saying, recognize that your words are being taken as either disingenuous or foolish, and are having the opposite effect of promoting your cause).
Another thing I’ve thought about is having everyone wealthier than me have a 100% wealth tax. And it’s a pity that people consider caring about inequality disingenuous and foolish while people argue that some people should be millionaires while others are starving. Millionaires should not exist.
