The fact that this is groundbreaking information, to some, is proof that women are so far ahead of men in the game. This is why women won't marry a man that makes significantly less than them. This is why Oprah says she'll never get married.
Women are good at selling you on the bullshyt, but they know better. A lot of women call men nice guys because a lot of stuff we accept, they would never accept.
They want your income to constantly increase, and sometimes will even nag you about it, but will tell you that they don't have to lose weight because you met her this way
She's going to sell you on love and all the intangibles, just so she can get the ring and access to your assets. You would think that she would at least keep up the act; most do not.
Out of guilt, some will not even end the relationship. They just stop sleeping with you, cooking, cleaning, Etc. Hoping that you will end it, or cheat so they can leave you and they can frame it as if it's your fault things didn't work out.
Even though the logic is heavily flawed, Women are far more logical then we give them credit for.
