Also they don't get taught critical thinking skills to understand why things are the way they are and easier to manipulate. That said my understanding of the general US education system is that it doesn't teach that (or much of it) anyways.
The US education system isn’t monolithic. There are lots of good public education systems in the US. It wouldn’t be the tech and economic powerhouse it is today (was yesterday?) if it didn’t have generally good public education. Part of the reason some people think “the system” is bad is because their particular state/county/district/school is bad.
Not just children. Anyone who isn’t rich, white, cis, straight, and Christian. If you’re not rich, then you must be a piece of shit, and you deserve nothing, not even the most basic human dignity (according to the 0.01%)
These kids already have jobs, they dont even need school. The ones with rich parents will still learn how to fuck everyone else over in their private schools, dont worry.
