People are racist because people do simple pattern matching and the people and groups have a bunch of overlap with the people and groups that did the border opening (which was also bad for the people hurt by the off shoring) who have a bunch of overlap with the people who were making the most noise about racism.

It's literally "owning the libs" but on a cultural level.

I'm not saying it's smart or right, but it doesn't take a genius to see what's going on here.

Who opened the border and what color were they? From my perspective these are more retroactive constructions of a history which justifies and explains many people’s declining economic statuses along with a whole host of elites who are supposedly responsible, with the most extreme blaming entire racial groups. In reality if there were anyone to blame it would be a roster of republican and democrat deregulators (especially reagan) who allowed corporations to grow more consolidated and politically powerful, alongside an unavoidable and natural specialization in the types of labor our country performs as it gets more advanced.
