Patients on Medicare/Medicaid plans have similar or worse issues finding therapists who take that insurance, so I am mystified as to why anyone would think that a single-payer system would be any sort of solution.

While in principle I think you're probably correct that providing good mental health services to employees makes for a more productive workforce, it's tough to connect cause and effect in a mathematically rigorous way. We just don't have high-quality studies in this area to establish cost effectiveness. And many employees tend to leave anyway for other reasons.

We really ought to break the link between employment and health coverage. That part never made any sense.
