I'm not an expert by any means but just happen to have some knowledge on the subject.
It really depends on the condition, how severe it is and if there are any compounding issues. Take something like depression as an example. In my country, UK, you'll often end up on antidepressants, and get a referral to a specialist if you're lucky. The specialist likely won't have the funding or at least a huge backlog of patients to work through so they'll be trying to get you out on your own as soon a possible, which means getting you to 'good enough'. As a result you'll likely remain on antidepressants when continued therapy would be much more beneficial and could take you off the medication. Drugs are cheap but time with a therapist is not.
A large factor is probably the increase of phone use. I've driven into a lot of shit looking at my phone.
