Wouldn’t they benefit from more people? Of course it would come with the condition of learning the language at an acceptable level and that being tied to residency.
Countries like Korea don’t have a cultire of welcoming people from outside and therefor you would have so many clashes that a huge number of imigrants - which is needed - would destroy the country. There is no one here who knows how to treat and integrate those immigrants. There are no programs for them, etc. and even if you know the language you still have huge culture clashes.
A lot of eastern Asian countries are extremely xenophobic in other words.
I think there’s a difference between being prejudice towards an outside group and not wanting your own culture replaced.
There is nothing inherently wrong with countries and their cultures not wanting to have others integrate. In the past this is what helped them survive.
It’s only a big issue in countries like the US that want to be a mixing bowl/melting pot and also are being xenophobic.
Do you understand the difference between integration and immigration?
Yes there is something wrong with not wanting to allow people from other cultures to integrate into your own.
