into so it makes no sense. The explanation is very simple. After the Jimmy Carter Experience a group of extreme right wingers got control of the government. Their ideological guide was the Chicago School and Milton Friedman.

The Chicago School insisted that we had to push down input costs to get inflation under control. They deregulated trucking (under Carter) and that helped push logistics costs way down, but the cost cuts were by and large taken out of the hides of truckers. Reagan opened the border for menial labor, things like meat packing. Absolutely shattered the unions, they needed scabs, Reagan delivered them.

By 1992 the DNC had fully subscribed to this extreme right wing economic theory and went whole hog on NAFTA. Substantive complaints were met with allegations of "racism" or "economic uncertainty." Capitalists used their direct or indirect control of legacy media to push a narrative that "29 languages are spoken down at the plant and diversity is our greatest strength."

As you have all personally witnessed, repetition and building the perception of a herd is all it takes for something to become "fact" for a leftist. Thus, over the course of a few decades, through very careful manipulation and repetition of propaganda the modern left has come to hold the exact same positions as the Chicago School held in 1981 when they began the march of Reaganomics. And at this point they are so committed to their position that they can't see it any other way than that they have always been in favor of open borders.
