The benefits of marriage are still present for poor and working class folks, even if one could argue that the upside ceiling is not as high as it for college educated people. I think it is best to separate marriage vs marriage with 2 kids and a house. You can have a DINK situation and rent (and save on rent) while saving until you can change your situation. If the situation doesn't change long term or the biological clock looms large then a couple will then have to come to grips with that, but poor and working class folks having to do things on a different time scale in and by itself doesn't justify the "economic" rationale for not getting married.
Sure, but that shouldn't be a requirement for prospering in the US. There is a moral question about whether that should be the case. If anything, it's a good set up
against black people, right? Historically, beating black people up about marriage is kind of silly considering that even when married generations of black people got screwed no matter what. That's probably what encourages people to go it their way individually. If marriage somehow made up for generations of lost wealth, a multi-generational propaganda war against the black mind and body, or the current psychological mess that we inherit, every black person would be married and happy as fukk.
When black people separate or divorce, you're doubly punishing them economically and then psychologically. That's fukked up. A white person can get divorced many times, cheat on their spouses, and still get rich and be looked up to? Donald Trump, Newt Gingrich, etc.
Also, imo, black people have to deal with a lot of psychological issues first...I hate to say it, but it's not exactly always conducive to healthy marriages. A lot of people should get some therapy before they get married.
