You haven’t been paying attention to what pE is doing. Every day medical services aren’t an international market.

You wouldn't be able to corner the market if it wasn't supply constrained (because it was already cornered by the AMA). The US doesn't accept medical degrees from other countries, has an absurd residential training program designed by a stimulant abuser, there are price floors called "certificates of need" where you can't open a hospital unless your competitors say you can, etc.
