The thing to remember in politics is that Govt's treat immigrants how they would like to treat the rest of us, if they could.
If they are compassionate towards refugees & migrants more generally, then we might expect them to be benign in their relations with the general population, when they 'crackdown' on migration, they really also want to 'crackdown' on those parts of the population who do not comply with their policies or do not support their prejudices.
