I thought the opening thesis was saying that there wasn't enough competition (stressor factors) and that's what was causing less capable and more dysgenic people to be born into a population. This is the population boom that is being posited as what is ruining western society.Thats all definitely at least part of it. But there are other consequences for humanity. The overcrowding, too much competition, and the decay of advanced societies while other more primitive societies around them are trying to thrive, etc. Its all an *ahem* cluster-you-know-what.
