> Educating children is incredibly expensive. The regions are quite annoyed that they pay to educate their children but that Tokyo reaps all the benefits. This state of affairs has continued for decades.
We see the same problem in USA states. State taxpayer dollars pay for some amount of public college education for state universities. These are typically called "State Appropriations", and varies between 30-80% of the student's overall tuition costs.
Back in the 1980's, taxpayers footed most college tuition using state appropriations, so college was "cheap" for students back then. Now (2023), (at least in my state, Michigan), state appropriations typically cover 20-40% of a college student's tuition.
There is concern with this though, because of what is called "brain drain". Citizens spend all these taxpayer dollars educating youth at colleges, then the graduates from U of M, etc all move out of state to California, Boston, Seattle, etc for big tech jobs.
Then the state of Michigan doesn't see any more tax dollars from those students. Which begs the question, why pay tax dollars for higher education if those who benefit from that education do not contribute back?
