It's similar to the entirety of human history, minus the last little bit. The notion of most men finding female partners is a relatively recent development. Throughout most of our history, most men haven't procreated. There was a story posted here a while back that cited DNA analysis to show that humans have roughly twice as many female ancestors as male ancestors. Apparently, the historical averages are around 80% of females that reproduced and only around 40% of males that did. It sounds like we experienced a brief period of middle-class prosperity that made that phenomenon far less pronounced and we're now seeing a regression back to the norm.
I'm not making a value judgment or saying we should want this disparity, just pointing out that throughout our history, it's mostly been this way.
