But I'll tell you what they don't want. They don't want a population of citizens capable of critical thinking. They don't want well-informed, well-educated people capable of critical thinking. They're not interested in that. That doesn't help them. That's against their interests. They don't want people who are smart enough to sit around the kitchen table and figure out how badly they're getting fucked by a system that threw them overboard 30 fucking years ago.
You know what they want? Obedient workers, people who are just smart enough to run the machines and do the paperwork but just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it. And, now, they're coming for your Social Security. They want your fucking retirement money. They want it back, so they can give it to their criminal friends on Wall Street. And you know something? They'll get it. They'll get it all, sooner or later, because they own this fucking place. It's a big club, and you ain't in it. You and I are not in the big club." - George Carlin
There's your answer to why.
The answer to how involves more details, but it basically has to do with pacifying the concept of critical thinking from our education system and all facets of american culture, and replacing it with rote learning. It's a lower form of intelligence, which is great for passing arbitrary tests and producing the obedient workers who are just smart enough to run the machines and do the paperwork.
The best thing you can do for a child is teach them how to think and learn for themselves. Grow their critical thinking skills and get them into programming or engineering. Teach them empathy. Oh, and buy them a bitcoin.
