It's not "redistributed". There aren't parental figures just apportioning money as they see fit. People are spending money on what they find valuable. Partly that's on the firm. Partly that's on salaries, particularly in places where creating competitors is easy and the incentives are good for people to want to take that risk. Partly on maintenance and the like. Then a chunk of the next lot must be given to the government or directors will be locked in jail. Finally, out of what's left, comes the money you're talking about. That can be reinvested, or pulled out. It doesn't "disappear".
