Does a guy have to make more money than the woman he is dating?

Many people say especially for folks that are very or just old fashion a man must make more than the woman he is dating. In my eyes no, a man does not have to make more money than the woman he is dating. In most cases it is a pride issue for the man and in the eyes of the woman's parents it is a disapointment. So, in our modern day and economy does a man have to make more than the woman he is dating?
