Obviously there are some places where you will have overlap between the different levels. For example, I don't think the federal government should be completely, 100% out of education, but rather should have a reduced role so the teachers can do their jobs and educate.
Obviously these ideas would be difficult to implement and are also idealistic. For example, some states are poorer than others so their tax revenue may not be enough. But even given that, I think state and local governments having more power would be better for the people. And no, this isn't some states' rights dog whistle or whatever (I doubt any of you would accuse me of that, but people have).
