This story i heard about 10 years ago through an acquaintance of mine who does shidduchim.
In short,many parents of boys or the boys themselves are looking for a shver who is/has a PHD—Pappa Has Dough(money)!
Going to the comment of rich girl should marry rich boy, in a recent story, the father of the boy wanted to prepare himself in the right manner so he went into hock to fix up their home, drive a nice car, and live the life of rich. His wife was upset but he said this way they’ll make a rich shidduch which they did only to find out that the girl’s side did the same. Anyway the kids got married and learned to live on their own while their parents were paying off debts!!!
