I understand just fine, I just don't share the naive "invisible hand" narrative. I think there are a lot of places where free markets make for better products and services, but not all products and markets are fundamentally the same, so I believe the same prescription of "just remove all limits to a free market -> all problems solved" does not work everywhere.

But Google can charge their "actual" users, i.e. advertisers quite a bit, and it is much harder to do any advertising without also advertising on Google Platforms, such as Search, Maps, Youtube, Adwords, etc. The wages may have only slightly gone up, but the profits definitely have gone up quite a bit, which shows that amount of workers and their pay has little to do with how much money can be made (which I believe is perfectly fine, because tech is not a place where I think free markets create a detriment to society).

I don't want to start a debate on free enterprise in general, just to show that free enterprise is not a once size fits all solution. My argument was just that the supply of doctors has very little to do with the price of medicine, because the market forces that determine price and can lead to lower prices in some markets do not work correctly in this market.
