Reimbursement for psychotherapy has been getting squeezed in the last several years. Reimbursement for psychotherapy is generally based on time: i.e. $x for a 30 minute session, $y for a 90, etc. Reimbursement for "medication management", i.e. prescribing drugs, is not based on time, but generally is a fixed amount. So the more prescriptions you write, the more money you make. Psychiatrists therefore focus on meds rather than therapy, as the reimbursement rates for therapy can't support a practice. Many psychiatrists don't take insurance at all bc they don't want to be "medication mills", so they charge $200-600+ per hour for therapy and only rich clients can pay. Psychologists and other licensed therapists can't prescribe meds, so they do therapy, but often make less than $60-70k a year. People don't want to go into psychology / psychiatry because of the stress of dealing with suffering people without having the tools to help them, and then getting paid relatively little (compared to other health care professionals)
This results in much of depression and other mental health being treated in primary care. PCPs aren't trained that well in treating mental health beyond what pharma sales reps tell them, so they wrote an rx and call it a day. 70% of patients don't respond to the first trial of antidepressants, but PCPs don't really know how to handle this
