This is true of most governments around the world.
I don't think the issue is so much with 'normal' people who migrate from one country to another, it's more to do with the way that modern nations work. It's standard divide and conquer. Get the masses fighting amongst themselves, to distract from what's really happening: the powerful exploiting everyone else.
We've had the same in the UK. First it's black and Asian people 'coming over here and taking our jobs', then it's the Europeans, then it's Irish Travellers, then it's [insert next minority group to oppress and demonise]. The poor fight amongst themselves, whilst the rich get richer. So convenient that the rich control the media.
