These articles are junk without also discussing divorce and children being raised by single mothers. Divorce destroys wealth(hurts gdp), and single moms in general produce sub-par results at best. Generally they are slut and thug factories. Try modeling that nerds. America is economically under-performing because of those two reasons. Expect more Trump like politicians in the future if you refuse to admit that women's lib is bad for the economy.

Edit: The ideological bias is showing in the downvotes. I thought you guys were all smart, data driven go getters? Use facts to prove me wrong instead of those primitive Trumpian emotions.
