Well, he’s right.
Open Borders IS an anarcho-libertarian idea, specifically intended to drive wages down.
The “race to the bottom”, as it is known.
Everyone needs to recall that the Unions under Gompers wrote the 1924 Immigration Act which basically ended the so-called “Great Wave” of immigration.
They did that because it meant they could improve wages.
Sanders may be the only honest Leftist out there. The rest of the Democrats - who used to be utterly opposed to mass immigration - have all drunk the Kool Aid and babble about letting the flood in.
In other words, they have abandoned the American working class.
Bernie is just sticking to the traditional line.
The reason the rest of the Rats have gone over is simple: the immigrants now are non-whites. And if there’s one thing the Rat party is desperate to do, it’s add as many non-whites to the population of the U.S. that it can. They live to replace the hated Evil White People with Saintly Minorities...who won’t be minorities much longer.
But until that happens, the gig will be this: the rich get REALLY rich, and the rest....fall further behind as more and more of the desperate show up.
There's also the Cloward-Piven aspect.
