"There's a reason education sucks, it's the same reason that it will never, ever, ever be fixed. It's never going to get any better, don't look for it, be happy with what you got. Because the owners of this country don't want that. I'm talking about the real owners, now. The real owners, the big wealthy business interests that control things and make all the important decisions. Forget the politicians, they're an irrelevancy. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They've long since bought and paid for the Senate, the Congress, the statehouses, the city halls. They've got the judges in their back pockets. And they own all the big media companies, so that they control just about all of the news and information you hear. They've got you by the balls. They spend billions of dollars every year lobbying, lobbying to get what they want. Well, we know what they want; they want more for themselves and less for everybody else.
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.
