From an evolutionary standpoint, monogamy favors low quality men and high quality women at the expense of high quality men and low quality women.
Given the quality threshold required to have multiple wives, monogamy thus benefits most men and few women.
High quality men suffer because they are unable to have additional wives, even though they could support them.
Low quality women suffer because they cannot become the second or third or nth wife of a high quality man, even if that would improve their situation.
Low quality men benefit because they are much more likely to marry than in a polygamous situation, in which their potential wives would instead be the nth wives of high quality men.
High quality women benefit because they can be the only wives of high quality men, whereas in a polygamous situation they would have to share their husbands with additional wives.
