LOL.....I totally understand what you are saying. You are 100% right in your thinking. Thats exactly how women are biologically wired to think.
On the other hand, men are wired to seek sex. Sexual attraction is the #1 reason men are attracted towards women. We can call it anything we want (objectification etc). Why would a man want a 2nd, 3rd, or 4th wife? Just because he wants to spend his money? or Just because he is feeling bad for this new woman? Of course not. It's the sex first and then everything else. Men check out women. Men are wired to seek beautiful women. Is this objectification? Sure it is. Is this natural? Sure it is.
Women seek out financially well-off men. So can we say this is objectification of men? Sure it is. Is this natural? Sure it is. Women want stability, security, emotional attachment and all that. At the end, it's a win-win.
