When people say they find the "very idea of billionaires" abhorrent, what exactly is the solution here? After the stock in your company becomes worth > billion you have to give it away for free? Because selling it means you are still a billionaire. I think there is something to be said about inheritance taxes and limiting the infinite perpetuation of wealth through generations but unless we are talking asset seizure I am not quite sure how you would do away with the Musks, Brins, Gates' etc. of today.
