You might
find this talk Nassim Taleb gave at Google interesting. He explains
antifragility (from his latest book, which I havent read).
His theory
with respect to societies argues in favor of small government to
reduce societal fragility. It is an argument in favor of competing
states theory and even for nullification. (Though I have a hard
time believing states can compete peacefully )
Bottom line,
the bigger the government the more homogeneous and fragile the society
and the greater the risk of a black swan event (a total system shock).
He sees the US and the world becoming more fragile as governments
become more consolidated and centralized.
