@duchess64 saidThe Left is too scared to make such an argument. It is far easier just to call anyone who opposes open borders as a bigot. In fact, they have about half the support of the country making such arguments, so why change now?
"Why the left should argue for more immigration – but not open borders
The US needs more immigrants to maintain current levels of economic
growth and welfare provision – but that doesn’t mean unlimited migration."
"A more plausible objection concerns immigration’s distributive effec ...[text shortened]... make sure that the
aggregate benefits of immigration are shared fairly within society as a whole."
The added bonus is, open borders also allows in law breakers, such as MS 13, which further pushes the narrative for the need for a police state and less freedom for US citizens. For example with each successive "shooting" provides more fodder for the argument of confiscating all guns from the populace.
