> minority enclaves with values that are fundamentally incompatible with the West
And this is a massively overblown problem mostly pushed to distract voters from those listed above.
Most of America 100 years ago was minority enclaves with values fundamentally incompatible with the "old" America. Worked out in the long run because we had a good run of a strong middle class. Money makes everyone merge.
But, the Republicans will just attempt to make the rich richer, and keep the poor and others isolated, then sell the story that the others are the ones keeping the middle class down, not the rich.
