Earlier quoted context omitted.
And how would you propose to set budgets, or teacher salaries? Should the teacher in rural Montana be paid the same as the one in downtown NYC? For that matter, "funding" is also "control" - do you think many states or cities are going to be eager to hand over their curriculae to the federal government?
Federal government does cost of living adjustments all the time, it’s not rocket science. Local control and national funding is a completely possible policy choice. There are tons of examples.
I can think of a few examples of national control and national funding, or local control and local funding, but not national funding without national control. What are you thinking of?
