They also get that way by inheriting wealth, by buying favorable laws and regulations, by anticompetitive practices (we've seen a few in the IT sector), and by other problematic behavior.
I agree that free markets are great in principle but your comments seem dogmatic - all free markets and only free markets. The conversation would be much more interesting if it was about the nuances.

Then their parents must have been billionaires, generating it with investments. If the inheritors divest from those investments, then they incur enormous income taxes. So it's likely to stay.
> by buying favorable laws and regulations,
Then it's not free market. There is no government system that is immune from buying influence and corruption.

Nothing is perfect.

Perhaps, but nuances do not drive prosperity. It would also be more interesting if you showed me a prosperous socialist economy.
