Sorry, couldn't resist.
You do make good points. A lot of people do choose a college based on the status it affords them rather than the actual education they will get. And you are also correct that college, often, does not really prepare you for a specific job. At least, a liberal arts college. But I stlll think it's an experience worth having - college teaches you a lot of things besides job skills, and of course even if it doesn't prepare you for a SPECIFIC job, a lot of jobs require a bachelors degree, even if that degree's not necessarily related to the job.
