It depends but in general, I disagree. If you have money and want to date the Brittney types you will have to have a big or interesting personality if you date a nerdy or average girl then yeah what you're saying is true. When dealing with above-average women especially if you have money the dynamics are different. Your Game has to be on point cause if it's not another guy will take her
Another rich guy not that good looking but he's got a personality and you can see that his girlfriend actually has fun with him and likes him
