Depends on how much the acquired knowledge (explicit and implicit), new contacts, friends etc. are valuable to you. People don't just go to college as an investment, to have well-paying jobs in the future. Of course not everyone can afford to do it simply for the knowledge and experience, but colleges aren't just supposed to manufacture white-collar workers, it is a way to have knowledgeable, informed, thinking citizens, in all areas of knowledge.
