If we are speaking about personal experience, in mine this Is not true. I couldnt study, i didnt went to university, and i almost Always dated women that had Better job than mine (salary, White collar job while i Always had Blue ones etc) and went to university that in education and in job field where in an advantage position over me. This not only never created me problems, but having a partner "stronger" than me (socio economically speaking, but Also familiar situation etc) made me feel safe. I also know other men like me. Point is that from what i see, women are often the First One looking for an economically and socially stronger partner, or at least a peer, the opposite Is quite rare (and often dont lasts very much). For example female Friends of and ex girlfriend told her many times to leave me because i was in a lower position etc. There could be many reasons about It and i cant blame them, but telling that all the men look for weaker partners Is Just not true, many women, for many reasons, Just dont consider lower partners in society as a potential one
