Money (or access to money) is often a proxy for a certain kind of stability and access to leisure, two things that many people strive for.
But the joke wasn't about long term, successful relationships. The guy was interested in looking attractive. That could have any kind of relationship goal, from one night stands to marriage, or even meeting someone who could introduce them to even more people.
Being attractive can be helpful to get to know people. But it can also be a curse. If you know really attractive women (like international fashion model types) you will learn that it can be very hard for them at times to find friends that don't just chose them for their looks.
Now if all you want are short hook ups, sure. But I'd suspect most people are looking for a lasting partnership where the other side likes them for who they are and both people have a good time being together. And widely desirable traits can paradoxically make it harder to find that, also because the other side has incentives to fool you.
