I was referring to subjects traditionally taught in school, of source. I'm pretty sure everything you mentioned is better learned by just LIVING.
Though I do believe some of those skills ARE improved via a good liberal arts education - as well as, IMO, the SINGLE MOST IMPORTANT SKILL learned in college: research.
I don't care what your field is, if you have learned to be an expert in researching, you can quickly pick up a huge variety of skills/information you need in order to adapt to your specific job. It's always been important, but now with the Internet this skill has become an almost indescribably important tool.
