Everyone should have a skill, but 4-year college is not for everyone. I got my bachelor's degree in French, and even went on and got an associate's degree in another area. My husband, however, just has a certificate in Telecommunications, along with 20+ years of experience in his field, and he makes twice, maybe three times, what I make doing what I do. He uses his brain in different ways than I use mine, and that's fine. What matters is that we both have skills that are useful out in the real world.
