He's talking about highly educated doctors taking jobs in private clinics instead of working in public hospitals for less.

Exactly. In countries with medical tourism this not only pushed the doctors to work for tourists instead of the local population that sponsored their education but also the brightest doctors to do things like botox, nose job or hair transplant because its incredibly lucrative. Fields that deal with stuff like cardiovascular deceases or children have become leftover fields where only the idealists and those who couldn't get into the cosmetic stuff specialize.
