So what do the US spend education money on? I would've imagined that teacher salaries would be the highest contributer to education cost, but for teacher salary the US is well behind everyone else.
In the US, I assume administration and materials (vendors for everything from desks to books). The US teacher's unions have been regressive for decades, wherein costs have gone up without the union being able to get better compensation. Ofc the employment benefits that teachers get is no sneeze. Retirement, healthcare+for your children until their 20s is something special (at least it was when my mom was a teacher).
