As long as Hospitals and Law firms continue to hire competent Doctors and Lawyers, this would be a win for society. More people getting health care or access to the legal system, at lower prices, would be a good thing for society.
And I don't see any reason why an increase in the number of Doctors or Lawyers would cause Hospitals or Law firms to hire incompetent employees.
That's pretty much how free markets operate. There is nothing wrong with it. The idea that X profession deserves the smartest kid in the room is nonsense if the profession has found out how to get along without that kid.
