True, in my opinion atleast half true. Good therapists know it but talk therapy is generally cheapest so insurance companies and health agencies push it to save money. It's difficult to determine how a mind works or how it is not working correctly. So you try the cheap option, doesn't work, try the more expensive option(regular medication), doesn't work, in some cases try expensive option(surgery). I'll agree the most expensive option (actually improving people's lives) is hardly ever considered an option.
