The AMA has been advocating for increased graduate medical education funding. I suppose they have some influence, but apparently not enough to convince Congress to boost funding enough to meet the demand.

I don't see anything particularly onerous about education and licensing requirements for lawyers. A sufficiently motivated student can complete law school and pass the Bar exam in a few years. So in practice there's no significant restriction on supply.
