Many opportunities can equal chaos. Think about the difference of a hundred years ago or more when men and women were limited to a few folks of their own kind as far as race, religion, education and ethnicity is concerned. This was before Hollywood inspired romance entered the picture.
A woman looked for a man acceptable to her family and someone she thought capable of supporting her and her offspring. The man looked for someone strong and fertile to raise his children. Beauty and romance were very secondary considerations.
Of course if you happen to live in the Middle East, things haven’t changed all that much.
