You are assuming that all tourism is a net positive for any region, which itself is a faulty premise. In a lot of cases unchecked tourism, immigration and foreign money only increases the income divide among locals and contributes to inflation and gentrification.

Not all these foreigners are living in tourist towns. They aren't staying for a week or two, but months at a time. They aren't staying in hotels meant for tourists, but rather competing with locals for apartments (a lot of them having turned into Airbnbs because of it).
