Do some Polish women prefer older men for money?
You must think so or you wouldn't have posted this question. Why did you have to single out the Polish women? If your theory is true then wouldn't it apply to women from other nationalities too?
Women often get the "taste" for older men because let's face it, they grow up earlier than we men do. When they develop the interest for the opposite sex we men quite often are still in the burp and fart stage. Ok, so some of us never leave that stage but nevertheless, women start dating those "older" guys because they feel like they have more in common with them than with their classmates. Maybe that preference tends to stick later in their lives? Who knows.
However, as I said IF you really wanted to know then you shouldn't have singled out Polish women only. Women are women, IF there's a correlation there, which I doubt there is, it would've been very similar to women from other countries.
Your question should really say: "do some people prefer older partners?" "If so, is it for the money or something else?"
I say people because I'm sure there are men who'd love to marry a well-off woman and never have to work again. Early on in my career I moved in with a lady who was making way more money than I did. I didn't do it for the money, I did it because I loved her. Several years later my compensation levels started to accelerate and now I was making way more money than she did. Again, she didn't stay with me for the money but rather because she loved me. Later on our hectic lives took a toll on our relationship and we split up and guess what, we didn't split up for the money either, no one "got" anything out of the split, besides two broken hearts that is.
My point is, if you come up with a theory, try to see how that theory would work for the "other side". More often than not you'll realize that in many ways we are more similar than we are different.
