"A high population density for thousands of years by means of cultural devices, such as vegetarianism. (and a rigid caste system?). The hippy movement did seem to favour personal spiritual development over conspicuous consumption of resources."
What? Indians are vegetarians because they're too poor to afford meat. The same lack of wealth leads to large families (can't afford contraception) which perpetuates the lack of wealth in the end as families have too many mouths to feed, clothe, and send to school. This is all a hippy conspiracy now rather than poverty and market economies leaving people to fail and die?
This whole thing had better be one big troll or my opinion of right wingers is going to lose so many points it will be lower than ice measurements in Greenland.
