Any modern country invest heavily in its future. There is no easier marker for that than education - literally laying groundwork for future of everybody.
Teachers should be paid and respected as much as doctors are, all levels, all age. But they should be skilled up too, every single one of them needs to be very good ad child psychology, no exception there even effin' gym teacher. If would arrange itself easily if they would be having doctor's salaries. They should be themselves role models, its #2 after parents usually.
US is not a modern country also in this aspect, its everybody for themselves, fuck the poor they didn't try hard enough and thats it. Wealth-based class society at best. Somebody has to clean pools and houses of rich folks anyway, it ain't gonna be their work colleagues.
