My personal beliefs are that it should be state funded (as intended), not federally funded. Apart from that, I think the social interaction is good and healthy, so I like the classroom setting as a whole. That being said, I can also see how giving more school choice and opening up more options and possibilities for education could prove to be beneficial for many students and help them to learn more, based on their learning styles and preferences.
Also, we really need to better evaluate how the money is spent. Athletic Directors and Principals should be qualified individuals, not just old football coaches. Superintendents should not be pulling in 250-300k while teachers are making 40k. Funding for certain sports or activities should not be as much as a dozen teachers' salaries combined while other sports and extracurriculars have to do their own fundraisers just to get the bare minimum equipment and supplies.
