AFAIK this takes place more or less everywhere, although America probably takes this to the extreme. I dunno about distant, hot and poor 3rd world countries but in Europe the more developed a country is the harder it is to get to a doctor (incl. a dentist). Some (reasonably competent) doctors travel to the west to invite patients from there to their licensed practice in non-EU Balkan countries because just getting a license in the west is too hard.
