The problem, though, is that the number of teachers we require makes that prohibitively expensive. We need to do both things. We need to increase the leverage of individual teachers, so that they can teach more students. To do that, we require technology. Then we can start paying teachers more.
Just fire most of the administrative workers. Everyone's a spendthrift until you want to spend money on teachers instead of administrators and multi-million dollar buildings and stadiums.
I would love to do that, and it would certainly help, but I don't think it's anywhere near sufficient to pay teachers as much as your average software engineer, for instance.
