I agree with that and I don't think these are necessarily contradictory. I've seen numerous well off patients receiving very poor care--because they fell into a trap--spent a ton of money on non-evidence based approach, and come running to me after various episodes of problematic outcomes--very common in substance abuse treatment. I'm simply describing that some marketing strategies can be very effective and sustainable in the long run, whereas others may be successful in the short run, but eventually it'll run afoul.
Opioid use disorder is a very good example. For many years, some of the leading (read most expensive) inpatient treatment programs in the country (Betty Ford, Serenity Malibu) advocated for a detox and drug free treatment program, even after decades of very strong scientific evidence that shows that medication maintenance is absolutely necessary for the vast majority of patients. This battle continues to be ongoing, and the Feds are starting to crack down on what essentially amounts of malpractice. Many overdose events are likely attributable to this practice, including several celebrity overdoses immediately proceeding inpatient stays.
Nevertheless, many of these facilities continue to attract well-off clients due to their existing reputation and connection.
You CAN be wealthy and make a lot of money by practicing bad medicine with good marketing. But I'm advocating that you make a lot of money by practicing GOOD medicine, which in the end is in greater need---I think a lot of people in the community are confused and see that two things are mutually exclusive, but I think in a world where snake oil is everywhere, having a practice of modesty and honesty that is strongly informed by science will get you much farther in the long run.
