Unemployment is very high, and there are no jobs for American citizens. He is luring people here with promises of jobs that don’t exist. These illegals are mostly illiterate, without any marketable skill. They will overload the health care system (what’s left of it) the school systems, housing, etc. Our dear leader is trying to collapse the system, create anarchy, and again, divide and conquer, ginning up race and class warfare.
But the American people will support this for fear of resistance being futile. Bad electoral choices since the 1930s has brought all of this to fruition.
