Having lived there for almost 10 years, most of it as a “local”, they also have a very real problem of foreigners coming there and destroying apartments or racking up debt and just leaving.
There’s more going on obviously, like the xenophobia you mention, and just straight up racism, and probably other things. So it’s a little more than just a cultural problem but that is a decent chunk of it.
It’s not, but you only pointed out xenophobia as the cause.
I’m opening the door a little and pointing out that it’s much bigger than just xenophobia that’s all.
