I would like to mention again "Funny Girl" starring Barbra Streisand and Omar Sharif.
Not so much rich, just to marry up.
How many Women really marry beneath their class?
A woman that marries a shorter , weaker , poorer guy is cutting across the grain.
Such a woman is subject to ridicule and her man to loss of respect.
Not only do men need to make more, women need men who make more.
Men who make a bit of money can find foreign women, who are marrying up just to marry an American.
Have you ever seen a website for women seeking Eastern European Husbands?
