Im not sure there's any correlation between young men who are sitting idle and what I was referring to. There are men who do not have children, some gay men for example, who are highly productive members of society. The selection bias that you indirectly refer to is already happening. And with the availability of ivf, what I am referring to is already happening as well amongst lesbian and gay couples and single educated women who haven't met the right person yet. And what's to stop it? If people who are smart, successful, but haven't found the right mate or don't want to get married, go gamete shopping and find the ideal set of genes, and produce the ideal child - how do other children without these advantages compete against them? My guess is that other potential parents then start going the same route, especially if marriage is on the decline anyhow. I don't think it leads to violence and truthfully it's not something I even condone without further thought.
