Cheap workers that are also under constant threat of getting deported (and have no real legal recourse because of it) are awfully convenient for many business models.
I guess the Democratic party is only incentivize to have illegal immigration? Although there might be incentive to fight against it at least for votes next time around, this issue lost the election (a non-dementia version of Biden would’ve recognized this, but his family loved the power so they kept him in)
The Democrats have similar incentives (see Biden’s admin’s actions, esp. deportation numbers), but they don’t use the anti immigrant rhetoric and don’t do the ICE raids for show because they also have the progressive, moderate and educated voters, and possibly also have scruples.
They sometimes say that they want less illegal and more legal immigration.
Biden’s dementia isn’t an explanation here, that’s really mostly just political ammo.
They act accordingly to those incentives.
