Tie in the fact that the average salary can't support the 'traditional' lifestyle, and the desire for 'traditional' dating expectations. And now you have men checking out for one of many reasons, for example: not making enough with the right type of career.

The typical “poor” person living in the USA lives in the lap of luxury (in terms of clothing, food, shelter, etc) compared to a serf in medieval Europe, a peasant under the Assyrians, etc. I mean, how many poor people have running water, electricity, Air Conditioning, etc.?
