And this isn't always possible. In fact it commonly isn't. I do agree the people who don't do anything and complain is stupid but many jobs don't have any opportunity for more and you become stuck.
There is a teacher shortage right now. The supposed pressure to improve things comes from where again? Who is going to be on a megaphone, chanting about poorly educated youth? Who gives a shit about illiterate, poor, people, except the manipulative assholes who get rich taking advantage of them?
Personally I believe the state wants poorly educated citizens
They spend lots of money on stupid shit. They take pride in working several low paying jobs, poor Healthcare, poor infrastructure. Basically, poor, uneducated people are perfect slaves. Why do you think it was illegal to teach slaves to read?
