The average person has a higher IQ, true, but the problems we face also require a higher IQ (and higher specialisation) than in the past. It might sound misant

The average person has a higher IQ, true, but the problems we face also require a higher IQ (and higher specialisation) than in the past. It might sound misanthropic, but the average person is average. Nothing wrong with it, morally or otherwise, but they won't be doing revolutionary work in specialist fields, they will be raising families and be happy. Like I said in my original comment, we can get by with a smaller population with western levels standard of living, and then only be constrained by genetics.
