Or there is a high barrier to entry. GP doctors in the US are both High Demand, and Low supply. But they have a very big barrier to entry, namely:

a) It's incredible hard to get into and graduate Medical School in the US

b) Medical schools have a very strict limit on the number of students, thus gating supply.

c) For only a little more work than being a GP, you can be a specialist doctor and make much more money.

Would not see this changing without a law change or something major.
