What does "power couple" mean?

As for this topic ,from my point of view,i think power man will meet power women normally,as we can see ,some rich man always find rich woman ,at least the women have big backgroud in her life,after married ,become power couple,i think it’s nature,big man always around big women in his social circle,at least i know some one of my friend,who want to get married with man,when she take the man meet her parents,her parents hope the man rich and power,the rich the better ,at least ,should be richer than the girl’s family.it’s really not a good culture ,but it’s exist in our life general.
