Man, if you think schools under capitalism churn out "obedient wage slaves who lack critical thinking abilities", you'd be completely lost for words at what happens when lack of critical thinking is overtly baked into the system, like in the commie states. I only caught the very tail end of the abysmal, soul crushing Soviet primary school education, and by the late 80s most adults were openly contemptuous of the totalitarian BS... But it was still enough to understand that this system was based on institutionalized, merciless bullying and a methodical dismantling of independent thinking of any pupil entering it.
Critical thinking and overall quality of education are not the same thing. You can be very good at teaching math, physics, geography, chemistry, biology while completely sux at "critical thinking" stuff. And vice versa.
Right, if people can't elect their leaders, then the leaders must stay in power by other means, such as bullying. Seems rather intuitive to me.
Another way of thinking about it is imagine if the bullies got in power and took over the whole state. What kind of state would it be? One without free elections no doubt
I'm not sure any governments are "capitalistic" per se, though many embrace markets to varying extents. As the sibling comment points out there Nordics are all VERY market oriented (more-so than the US/Anglospehere) and have strong welfare states. As for the US it varies a lot state by state, and most of the really egregious shit is done by municipal governments.
But none of that really matters because the US/West was never carting people off to work camps for something their children let slip in school, which the USSR and GDR did for decades.
Isn't it also true that in a truly capitalist system the capitalists (meaning people with capital, the rich) would be in power, meaning they could also "buy" the government?
There are many different flavours of capitalism. Sweden bullies poor people far less than North Korea or Cuba or Vietnam does, despite being a capitalist society.
Not to mention, as another comment mentions this was to give them a sense of responsibility early not to get child labor
