You are making a generalisation. It's not the first post of it's kind so I'll keep it short. I'm not rich by any stretch of the imagination but I never had problems getting girls in school. If anything guys who aren't as "fortunate" bring it upon themselves. Money may never have been an issue to the girl, but because you are so fixated on it, issues arise. You tend to feel smaller as compared to your richer friends and you start to blend into the background preferring to wallow in self pity. I've never let it bother me and trust me, you'll find that it's appealing to women that you don't. Having said that you can't be on the extreme end of poverty either. The vibe you want to give off is that while you aren't rich now, you'll be working towards a brighter future. Ambition, determination and confidence are traits even money cannot buy.

If anything this is a generalisation. I'm not rich but I have better dining etiquette than some rich blokes I know who still don't know to work through their cutlery from the outside in. Some talk with food in their mouths while others are sloppy eaters who share a fair bit of their dinner with the table cloth. Money can't buy class. Having said all that, I believe that one can actually be rude or lack etiquette with a bit of class. It's hard to explain but you'll note that guys with confidence and charisma can burp in public and still get chicks. Guys who don't have confidence will be looked upon with disgust if they did the same. Seriously, your attitude matters most, more than wealth.
