Liberal Ed vs. Vocational Ed

I think we need to have a liberal education. We need to be able to communicate ideas across boundaries like culture, economic status, ethnicity, individual expertise, and education level. I think that if we all don't have at least an introduction to subjects like ethics, psychology, sociology, history, math, science, music theory, literature, language usage, and rhetoric; then we will eventually create little niches of people that cannot communicate outside their circles. We can't have a democracy if the people cannot understand each others wants and needs. I don't think we all need to be experts in everything to at least be able to understand the gist of another person's ideas, but I do think we need the same foundational knowledge.
