If the citizens of California wanted to fund a given social program, such as free college education for all its citizens, and the citizens of Tennessee only want to fund public education through high school...
But isn't that the way it is now? I am not aware of a federal mandate that says states must provide free college education, nor do I believe that any federal taxes are funding free college education.
On the other hand, would you advocate states deciding how much education they would provide. Maybe Ohio would just say "No education for anyone unless you can afford private school". Sure it would be the states right to do it, but do you think it would benefit the country as a whole to have uneducated Ohioans running amok?
How much education do you need to run a mok? Those things practically run themselves.
