I don't think that's coincidence. Cheap air travel opened a window on the world and absolutely ruined a lot of places. To the point that if you haven't visited Machu Picchu the consensus is that you haven't really lived. Tourists are roaches, they bring some much needed income to some places but they utterly ruin others, crowd out the locals, cause living spaces to be converted into hotels and make it impossible to buy food and drink at normal prices for the people that live there.
