The first thought that came to mind here was that emphasizing heritability will lead to racism, nepotism, sexism, inherited classism, etc. This is merely an observation independent of how strong heritability actually is. Then I realized that the developmental / nurture model favored by most of today's intellectuals combined with brutal meritocracy does the same thing, but with a layer of personal blame and a huge quacky market for developmental aids of dubious effectiveness. The fundamental issue is that society has become much more competitive and stratified, with the easier middle class path vanishing. That is going to create brutal competitive stratification regardless of what model (heritability or nurture) best characterizes the rules of the game. Yet paradoxically we are in an age of extreme abundance where goods, services, and money itself (low interest rates) are cheaper than ever before. Abundance is creating scarcity. Something is very very wrong.
