> record high illegal immigration levels that we're seeing today
As of 2022, the undocumented population was still about 10% below its 2007 peak. [1] The population of the US grew by 11% over the same period, so as a fraction it's well below the recent maximum.
Some of the statistics at the border increased massively in recent years because a lot of immigrants are now turning themselves in as refugees. [2] This allows them to "ride the disfunction" in the backlogged immigration courts, granting them legal work authorization and deportation protection in the meantime. If we fixed the disfunction, they would just stop turning themselves in once again.
The level we've "agreed that we're okay with" is far from set. Every time we've tried to set it in recent years [3], restrictionists like you have spared no tactic to gum up the works. That's because you figured (correctly) that the level of legal immigration that we would compromise upon is higher than the level we currently have.
Restrictionists are the primary reason we have a vast underclass of semi-serfs.
