Well you can find out about job prospects for people with two-year degrees. There are various websites that can give you information.
But I don't see why pursuing a 4 year degree program should stop anyone from marrying. You could marry and study at the same time. Or you could work part-time, study part-time, and get married too. Why should these things be mutually exclusive. The problem is that the longer people wait, the more they don't want to marry. And getting married earlier (late teens / early twenties) should be encouraged. If you have the means. Waiting until you're in your late twenties / thirties is not good in my opinion.
