@SoloSera So you think children should learn from machines, I take it? We are all different, which means all teachers are different. Some will inherently be better than others. The better ones provide better education, which means they are worth more, which means the school needs more money to employ them. Schools get bigger budgets depending on performance, meaning having better or more students becomes a competition.
This is the case in USA as well, I believe. It's just a facet of capitalism. Don't know if the Japanese school system is a relic of American influence after WW2. ¯\_(ツ)_/¯
The only feasible way to solve it would be to equalize learning through machines, and thus equalize school budgets.
I live in a fairly socialist country. While we
don't have competing schools, every
single school I went to (there were quite a few😑, due to moving around a lot) complained about lacking funds.
