Like attracts like

My mother always told me (with regret) that money attracts money. Since we didn't have any, I didn't find any when I got married. What she didn't tell me, though, is that the really rich only marry people who share both their money and their name. How else to explain the fact that the boring and tawdry, but very, very, very rich Paris Hilton is about to marry a man named Paris? Yup, she's going to marry the even richer Paris Latsis, heir to a Greek shipping fortune. They weren't kidding when they said the rich are different -- or did they mean the same, at least as to each other?
