1) There are huge numbers of careers that require a college education. I can’t think of any careers where a college education disqualifies you (although someone might be able think of ONE).
2) A good chunk of 18 year olds don’t know what they want to be when they grow up. Getting an education is the best bet for success.
3) A college education is also a college experience. You can’t quantify that in dollars. Even though I went through some rough times and was poorer than dirt, I would not trade my college experience for anything.
If life was all about making/saving money, I would never have had children. Some things are just worth the cost. 🙂
