Maybe we can just create a lower underclass that we make too stupid to care for growth by subjecting them to alcohol during pregnancy and provide them with drugs that will simply allow them to be content by being.
Likewise, poor educational outcomes not caused by FAS are also correlated with low socioeconomic status of the parent(s). And we already have the "content by being" drugs -- tobacco, alcohol, and television.
If that doesn't look like a permanent underclass that we're snowing with Soma, I don't know what would.
Huxley is definitely on my top ten list of favourite authors.
