I'd be curious to see how this actually plays out in some detail. Are the usual suspects of faltering educations systems and lead exposure to blame? Is it recreational substance abuse? The dissolution of the extended family? I'm not sure I buy the argument about people with less IQ potential having more kids. Or maybe is the IQ test a big friggin' waste of time?
The problem is not people being uneducated. The problem is that people are educated just enough to believe what they have been taught, and not educated enough to question anything from what they have been taught.
