And while you may be uncomfortable with being a billionaire, it is a bit immature intellectually to wish to take this away from others, who are in fact legally earning it.
And here is another concept you need learn, since you believe they did not actually "earn" their wealth. Remember, there are two ways to work. One can 'work hard', or 'work smart', or both. You are only concentrating on the first one, and not the second. And perhaps you fail to realize that the 'work smart' part is all about one's time, which still belongs to the individual. And time is an individual's unit of value I believe.
And if one would throw out the right of Property, and Rule of Law, one would get perhaps what you yearn for. I, for one, prefer not to see it.
