I'm not touching the sexual part with a 10 foot pole cause it bears no relevance in my opinion either. But I do think that many young men are economically disenfranchised in The States.
Edit: In my comment any mention of 'men' should read "and women". I don't mean just males which is another reason I don't think it is important to address the sexual disenfranchisement part.
A quick google search suggests black men are less sexually disenfranchized than non-blacks.

It also isn't necessarily true that the change in the level of disenfranchisement is due to growth, or change in anything having to do with the economy, so much as due to changes brought on by the civil rights movements. Things can change on a societal level without being impacted by or impacting directly things at an economic level.
The social instability mentioned in the parent is still going on even with these advances. Just saying 'its better than it was' doesn't make it not a thing.
