No dummy, foreigners who take advantage of the weak currency in these countries can simply price out locals because they can and do buy/rent at higher prices. It’s not a ‘skill issue’ for the locals, it’s a direct consequence of unequal exchange and destabilization (past and/or present) in those regions. As someone who espouses the values of capitalism you should at least know how markets work.
You are being intentionally obtuse here. Obviously gentrification carries downsides when the people from that neighborhood cannot afford to live there anymore. The neighborhood “improving” doesn’t help the original residents if they can no longer afford to live there. Tourism and retirement economies can carry benefits. They do bring money into regions. But I know you can understand that there are downsides. You’re just being annoying on purpose.
Tourism and retirement economies create a community where dead-end service jobs are basically the only option. Where does that money go? To businesses, to landlords, but certainly not to the workers. Their costs increase as business adjust prices to what people are now willing to pay.
It depends on the region and how it is conducted. I have visited the Galápagos Islands, for instance, where the economy is entirely tourism-based and provides more opportunity than much of the mainland. It supports local hostels and the local agriculture industry. The locals actually want more tourism but it is limited because of ecological concerns. This is, however, due to strict regulations keeping investment in local companies rather than international chains.
