>And outside of industries with government enforced perversions of simple "supply and demand" forces (we're not talking Nth level effects here) this means more access to the service or lower prices or both.

Greater access at the expense of the number of people employed is not necessarily a net positive. In the case of healthcare, the data is fairly clear that higher nurse staffing ratios lead to better patient outcomes (read: decreased chance of death or serious complications). This is particularly true for ED and ICU nurses.

Also, in the case of healthcare, I'm fairly certain that hospitals in the US are legally not allowed to turn patients away. So "lack of access" is not currently a problem for serious medical emergencies.
