One job that doesn't require a college degree and is in demand is Sales Representaives.
I'd agree with Greg - I was actually having a discussion with someone yesterday about what one skill would you like people to have. Along with the usual suspects of work ethic, willingness to learn etc.... (not skills per se) we agreed that an ability to sell was top of our list.
It's not just for sales roles though - I'd love eveyone that works with me to have an understanding of, and willingness to, sell. I think it's one of those skills that if you can learn to do it well then you'll always be employable.
