From what I can tell, a big part of the problem in Europe is that people seeking asylum are prohibited from making a living (due to widespread belief in the lump of labor fallacy) and so have to be dependent on welfare.
>asylum are prohibited from making a living
This is exactly how we got here. We allowed them to work to make temporary asylum permanent migration.
Yes and when a government tries to do something about that (like Spain granting temporary permits so they can work and pay taxes) it angers the right even more.
