Of course the US market is highly regulated and so the market is not free to lower prices. Of course the AMA is a racket. Of course needs of certificate are abhorrent.

You're conflating 'capitalism' with 'free market'. You can have either without the other and OP was calling out 'capitalism' specifically.
