Dear Leader has already been talking about instituting some kind of program to formally permit cheap imported labor in "critical" industries like farming, construction, and landscaping. And why would the regime ever want to fix any root causes? Pournelle's iron law of bureaucracy applies to autocracies as well. The Republican party has been drumming up support on this bogeyman for decades. Remember when there was a bipartisan immigration bill up for vote before the election and Tramp insisted that it be killed? That's the fundamental dynamic right there - their cultists crave human suffering, not effective policy.
