You're more generous with public indoctr... errr, education than I am. IMO, any public efforts should be completely funded locally by those affected. It works in much of the world, while in other areas it's more dependent upon charity.
Much of the problem with intelligence is due to our current education systems. They teach facts (or what they want you to know, whether true or not) so you can pass tests and they can keep looking good in order to get their funding. Critical thinking has been lost, except where a few standouts break from the herd or parents embrace teaching it themselves, either through homeschooling or by spending a ton of time walking their kids through the state system. We opted for the former, and never looked back. It paid off nicely, IMO.
