That's not what's happening. Globalists buy up our media and technology companies and use them to shut down the free exchange of ideas. They also take over our manufacturing and offshore it to low wage countries. Then they flood the domestic labor market with immigrants. With a glut of workers they can then terrorize anyone who steps out of line with threats of job loss if they criticize the process. That's what political correctness is. A system for promoting "freedom" that is in effect serfdom.
And yeah, I want to wall us off! The wall just got ten feet higher!
Funny, we really seemed to collapse when George Washington and James Madison and Andy Jackson and Abraham Lincoln and Teddy Roosevelt “walled us off.” Yeah, the economy just sucked then (US went from 4th in the world to 1st in the world in production from 1865 to 1900, the whole time with tariffs). Employment shot up, average income shot up, Inventions were off the charts.
