It's pretty easy: allow prices to rise a bit and people will enter the field. I think existing ones wouldn't mind a raise considering some of the stuff they have to deal with
Have you seen how much it costs to see a psychologist (including what insurance is covering)? It's several hundred dollars an hour. That increased price is also an increased barrier for entry, to get treated. Free market dynamics are horrible for healthcare
it's already prohibitively expensive for most people since most insurance doesn't cover it. Doesn't really seem like a solution.
Edit: in the US. Can't speak for other nations.
Due to the Mental Health Parity and Addiction Equity Act of 2008, most insurance does cover it. Depending on the patient's particular conditions there may be limits on the type of care and number of sessions. In many areas there are also practical access problems due to a shortage of network providers who are currently accepting new patients.
There’s a shortage of network providers because the network tends to pay peanuts, they mandate the usage of only a few treatment methods that may not be effective for the client, and make actually getting reimbursed a massive administrative headache (think many hours a week writing billing appeals instead of seeing clients). Medicaid is even worse and pays bottom of the barrel. The restrictions and complications that come with insurance repayment have lead a huge amount of providers to not bill the medical system, for simple personal economic reasons - they can’t afford to feed and house themselves if they have to deal with the lower rates and overhead of dealing with insurance.
