Could you rerun this analysis using only the "physical attractiveness of the people" (and not adding "rich + educated" to the equation) visiting each place, @levelsio? I think the current result is heavily biased by wealth. The combined estimated monthly cost of living for the cities in the first group is €52,255, compared with €22,212 for the second group. So the result may simply reflect the fact that wealthier people tend to visit more expensive cities. If you split people solely by physical attractiveness, the cities should fall into two essentially random groups, so there would be nothing meaningful to infer from the city lists themselves.
