Maybe because have a gigantic money head start is basically a must and not something that the mere mortal can have because of the actual thing that they are criticizing it?

You can be rich, put that money somewhere where someone “manages” it for you, fuck off to a desert island for 5 years and when you come back you are richer than before. And you didn’t do jack shit for that money. Do you think that is fair? And most importantly where do you think that money “is coming from”? The answer is that it is skimming from all the hardworking people that generate profit for the company while only getting paid a small fraction of that.
