I think it’s because they want to keep us stupid and withdrawn from the world as a whole. The US is kind of a giant prison, but with some shiny things to distract the more well off inmates from caring as much. For those who are poor, they’ll be aware but have hardly a network to figure out how to escape. Language is incredibly important and also allows you to think in different ways depending on what languages you know; gives different perspective. They don’t want us to think.
