Simple things which have been instituted in school boards worldwide would be great starts. A national curriculum, some uniforms, longer school years or days and a total remodeling of how we teach certain classes (history, science etc) would go a long way.
It is sad that people do not realize that simple measures would go a long way towards intellectually fixing our ignorant masses. We have millions of people in this country who are unemployable as anything other than low level employees. We have millions more who are simply unemployable and it all starts at the education level.
This is something I've stressed for a while now. The problem with ignorance in America comes because we simply do not teach kids to love learning. We teach them what a computer is before they know how to read books.
We are perpetuation a cycle of trash. We teach kids to dress like trash from the moment they enter school and so they act like trash. Label theory. But no, what people want is the freedom to teach their kids whatever they want to teach them. You have people complaining about their kids being taught about evolution FFS. You have people complaining about their kids being taught about proper sexual hygiene.
