This point is absolutely true. Marrying for love while ignoring $$ is the domain of the young or the foolish.
A friend of mine has two daughters. One of them has acted like trailer trash. She had an oopsie kid, then finally married a guy who doesn't want to work, so she's the one out there bringing home the bread (fortunately she likes her work). On top of that, the guy has a genetic problem which was passed on to one of the kids she had with him, and which may shorten the kid's life.
The other daughter was described by her mother as a princess. She knew, from a young age, that she did not want to marry a poor man. She has been married for nearly 10 years to a young man whom she loves, who loves her, and who ALSO makes a good salary. And she just had her fourth kid.
When I was her age, I didn't want what she wanted, but I have to say now that maybe she knew something which I didn't at that age... and I have to admire her for knowing what she did want and then getting it.
