I think that Trump and his party are driven purely by personal benefit and greed. The policies of Trump and his cronies reflect this and show how they want to control all the wealth among a ruling class. However, I don’t see how deporting immigrants (employees) would help this cause
Are they doing this for popular support? Why would they prioritize xenophobia over capital? Is it simply that they’re hateful and scared?
You’re always going to a chunk of political support by oppressing minorities, anyone considered ‘other’. A percentage of people are always going to hate, mistrust and blame the out-group for everything wrong with their lives, and this makes them very easy to lead round by the nose.
Stoke enough hatred, and people will gladly give up due process, human rights and social equity in the name of oppressing those they see as the enemy.
And once you can do that, large corporations can exploit the absolute shit out of the population, way harder than they could with all those pesky laws, regulations, oversight, etc. They can use slave labour from the concentration camps, steal the land and wealth from the people they kill or imprison, and they can rewrite laws to suit themselves, secure in the knowledge that anyone opposing them can simply be disappeared off the streets.
