In all combat sports, there are weight categories. This ensures a featherweight isn't beaten up by a heavyweight. If a guy wins 100 fights straight because he is good, it is okay, because they are fair fights (assuming no doping, no biased judges etc). But in business, this is not the same - one set of rules for big businesses and billionaires and another set for small biz/startups. This is after one becomes a billionaire, which many billionaires use unethical (at best) and illegal (at worst) steps to get to.
I guess "being a billionaire" in itself is not immoral - how one gets there, and what one does to stay there is what defines how immoral the person is.
