You seem to have confused the comments. I'm an employee living in one of the highest CoL areas in the world. But I know quite a few who run small businesses here and make use of that fact to the fullest extent. They can charge insane amounts of money for minimum quality work that wouldn't even put enough food on the table, let alone afford any luxury at home elsewhere. In the countryside I imagine you'd actually need to bring some talent or do quality work as well and not just make use of unsaturated business markets in overeducated areas.
