Yeah fire definitely requires a good salary as I said.
I think it depends, you’re not always hurting the locals. Often there’s expat areas in cities that are more expensive but more local areas stay cheap. Also you can support locals by buying from there businesses. I’ve been travelling southeast asia lots and the majority of locals tell us they like the tourists and expats because they allow them to make much more money.
Yeah that could definitely be an issue. On the other hand though its a great way to learn a language and meet people living very different lives. Also most young people nowadays speak english and want to speak it with foreigners so its easy to mave friends that way. Plus there’s lots of expat groups and meetups so actually pretty easy to find likeminded people.
