Does being a rich guy attractive to girls? Watch
Some girls will be attracted to guys with money: sugarbabies, gold-diggers and girls that are looking for marriage & financial stability to raise children.
Other girls may consider much richer guys off limits because they consider them intimidating, know that the wealth disparity risks them being viewed as gold-digging inferiors or believe that there will be an attempt to buy them (exchanging money for power and control in the relationship).
If one person is a spender whilst the other is a saver, that's a recipe for long term unhappiness in the vast majority of households. Or if both of them are spenders, that's also a recipe for dissatisfaction - in most households.
If one person is somewhat of a saver or investor and the other is somewhat of a spender, then a large amount of money will lubricate that aspect of their relationship.
If someone is a self made millionaire, then that person is very likely to have certain skills and experiences that will tend to make them a more attractive all round proposition than someone with no job or a low paid job that spends most of their spare time playing games on their X-box.
