The author provided data and graphs to highlight the problems in America he believes are being caused by a root problem of society having low expectations for men.

He doesn't provide any data to reflect what society's expectations are. Those are just his thoughts.

That's a big distinction.

The author provides no direct data, but cited a large number of peer reviewed articles and books. For example:

In a fascinating 2012 paper titled Sexual Economics, Culture, Men, and Modern Sexual Trends, the psychologists Roy Baumeister and Kathleen Vohs wrote:

“Although this may be considered an unflattering characterization…we have found no evidence to contradict the basic general principle that men will do whatever is required in order to obtain sex, and perhaps not a great deal more. (One of us characterized this in a previous work as, ‘If women would stop sleeping with jerks, men would stop being jerks.’) If in order to obtain sex men must become pillars of the community, or lie, or amass riches by fair means or foul, or be romantic or funny, then many men will do precisely that.”
