He meat he’d unite the US with the 3rd World.
Seems like he is doing rather well at that.
That's the eventual goal. An elite lording over a working class, no middle. The US could stand in the way of the elite, but it won't.
It's no accident that Congress passed tax and environment regulations that tended to offshore the good jobs. Part of leveling the (world) playing field. standard of living in the US is purposely being lowered. Out of control spending, race division, soft on crime, whimsical application of law by courts, all sorts of tools in the government tool box to the same end. Enrich the corrupt governing class at the expense of the public, and condition the public to "take it."
The institutions are a success in their own minds - the goal being to merge the US with the world. The same conduct and results are failure if the goal is a strong nation where personal liberty is respected and protected.
