In GENERAL SOCIETY, its said that a MAN should be able to support his family. When a woman is the one working, and supporting the family, and the man, this is frown upon. I believe that its not as important as it should be, since for many years, this statement has been turned around. There are many women, that to this day, are looking to be in a relationship, and be married, solely to have a man to take care of them.
As much as I believe in Love, and marriage, I do not think that a man is a "financial plan" as you stated. A man can work, yes, BUT women are also capable of working, and many make much more than men do these days.
