I think a lot of you miss what I believe are statistically backed truths about income rates/socioeconomic status and relationships, mostly people stay in their group, that's what accounts for all the girls in the lower income neighborhoods with lower income partners. Part of that explains generational poverty, and it's oppressive cousin of the other 19/1%, who tend to date, marry, and procreate in their same socioeconomic status. Now, to a degree, based on income levels, which is based on years of male dominated society, males tend to make more, which means on average, they tend to date, marry, procreate below slightly below their income range.
So, most people are already "staying in their lane" so to speak, which isn't always a great thing for anyone in terms of experiences and diversity. I look at it like when I was in high school there were three girls I loved, and at that time they were all I knew in terms of what I was attracted too. Now, 10 years plus later, I know there are many other kinds of women in terms of everything, from looks, to culture, to personality. Don't limit yourself.
