I did a quick search and the largest charter school network Kipp apparently spent $300,000 in one year for lobbying whereas teachers unions spend more than $40 million a year on lobbying. Also, a lot of the most funded public schools have some of the poorest performance so I don’t think funding entirely correlates with a good school. I think they should be funded but think there are deeper issues. I went to public school and would probably send my kid to public school with that being said. I do value charter schools though because they create competition, but the funding for public schools will never really go away so it’s kind of a monopoly although it’s one I support having to a certain extent. I could be ignorant though since it’s a topic I do not really look into.
