Women often are too fixated on income when it comes to relationships. This applies to both the income of a prospective man and their own. It makes sense that they want a man who makes a decent amount of money if they want a family (no burger flipper is going to be able to support a wife and children).
But beyond a certain point, it becomes less of a genuine need and more of a point of avarice on the women's parts when they want even more income for a certain "lifestyle."
For a family, you need a place to live, transportation of some sort, food, clothing, and many other expenses.
For women who demand far more than what is needed, it becomes clear that their "requirements" become a point of vanity. When you want more money for a bigger house, a more expensive car, going out to eat all the time, and yearly lavish vacations, the "I need a man who makes X amount of dollars to raise a family" is clearly not true.
And income requirements become far more of issue with women setting their bar based on how much they earn. Few women will want to marry a man who earns less than them. So they price themselves out of the market.
And often, a woman who is making a higher amount of money than average is not using those extra earnings to save as a nest egg to start a family, but rather to support her expensive lifestyle. A lifestyle she wants continued with a future.husband, thus increasing the "requirements."
Therefore, a woman who simply makes more money does not prove herself a good woman if that money is spent too quickly. Rather, a woman shows she is a better quality woman for long term relationships if she is capable to being able to stretch out the money she has available to her as much as possible (whether it be her as a single woman or a married woman with a single/joint income).
Income alone means very little if it is frittered away for all the wrong reasons.
