Which is my point exactly. Everything gets more complex and requires more grey matter to be able to do it successfully. And more and more of society doesn't have the grey matter necessary, and start to fall between the cracks.
You then have an addition process at work, assortative mating. Which basically means clever people are more likely to have kids with clever people (and produce higher than average intelligence children) and vice versa. If 90% of jobs require X level of intelligence and those below that end up largely on benefits, partners are going to be selected from your immediate social circles, which will be sorted by intelligence beforehand, by jobs and education (or lack thereof). So even the random nature of DNA transfer will be dulled by the pre-sorting of people into groups by intelligence before they select who to have kids with.
So increasingly you will end up with two groups - those capable of getting on in modern society, and having kids who can get on as well, and those who aren't capable of managing the modern world, and neither will their kids be, largely. Plus of course there will be a lot of nurture as well - a dim child from intelligent parents will be pushed at school and got through university and probably make a go of life, a similar kid from a not so bright background won't have the same support to force them onwards. So you have both nature and nurture working in conjunction to create separate groups within society.
I agree entirely. Then the added issue of the less able generally having more offspring per capita than the more able.
