It's simple. There was a struggle in America between Global Leadership of the Rules-Based International Order™ and white supremacy, and white supremacy won. When your goal is to whiten America and your ideological framework is an existentialist one like the Great Replacement, you're perfectly happy to run over democracy, alliances, leadership, even economic competitiveness. Racialized nationalism trumps (no pun) everything else.I don't understand the $100K HB1 thing. When ICE raided the Hyundai plant in Georgia and arrested over 300 skilled workers there to train Americans and jumpstart the plant, it was rumored that Trump understood the mistake it was and asked the workers to stay. However, they were treated so poorly and with so little dignity that they refused and went home, causing the progress to be severely delayed. I laughed and laughed and laughed about how the US shot itself in the foot with EVs and shipbuilding but I understood that was an isolated episode and a small setback.
So how could Trump be deliberately making this mistake on a national scale? It benefits all the countries that are US alternatives in the EU, Australia, Canada, etc... in that they will now take more skilled workers who want to emigrate and it also benefits the countries of origin for these skilled workers like China and India because worker retention will be strengthened with the US mosly removed as a possible route for braindrain. It benefits China more because China is a modern society and its cities are top in the world so worker retention is stronger than India, where people proclaim they'd rather die than be there. I don't understand what Trump wants to accomplish. I couldn't really laugh this time; I just stared with an open mouth. This is a literal example of when something is "so stupid it's not even funny."
The social media ideologues who subscribe to this have a rebuttal to the economic arguments for immigration that sums it up perfectly: "This is my country, not your economic zone."
