These people are rich because they provide a good or service that everybody wants. Whether they got to that position through hard work, timing, motivation, or luck isn't important. The way that the system works benefits everyone.
Look at Michael Jordan, if we (whoever "we" is at this point) were to suddenly say "right, your basketball skills are subject to luck, you don't work hard, we're not paying you as much", and, as a result, Jordan stops playing basketball... who's really benefitting? Not Jordan, his wealth is either going to decrease, or the amount of work he does has to increase, and not his fans... you know, the people who actually made him rich in the first place. The people who decided that they valued his sportmanship enough to buy tickets to watch him, buy merch, etc. If MJ no longer played basketball, all those fans will be deprived of a service that they held dearly.
Never envy a man with more money than you, you'll will not be better with the money than he is. No man is worth more than his money.
