The American experiment is fragile. It has always been fragile and always will be fragile because it is so extremely unnatural. ‘Unnatural’ in this context means in conflict with human nature. Jonah Goldberg has described the fragility of the American system by comparing it to a garden hacked out of a tropical jungle. A garden surrounded by jungle is unnatural. The gardeners must tend it with unremitting care lest the jungle return.
Treating our fellow human beings as individuals instead of treating them as members of groups is unnatural. Our brains evolved to think of people as members of groups; to trust and care for people who are like us and to be suspicious of people who are unlike us. Those traits had great survival value for human beings throughout millions of years of evolution. People who were trusting of outsiders were less likely to pass on their genes than people who were suspicious of them. People who were loyal to their tribe were more likely to pass on their genes than people who stood apart.
The invention of agriculture and the consequent rise of complex societies exposed another aspect of human nature that had enjoyed less scope for expression in hunter-gatherer bands: acquisitiveness, whether of money, status or power. Whatever its evolutionary roots may be, the empirical consistency of human acquisitiveness over the eons is impressive. The open-ended desire for more money, status or power has been natural; to voluntarily limit one’s wealth, status or power has been unnatural.
The combination of acquisitiveness and loyalty to the interests of one’s own group (be it defined by ethnicity or class) shaped human governments for the subsequent 10,000 years. The natural form of government was hierarchical, run by a dominant group that arranged affairs to its benefit and oppressed outsiders to a lesser or greater degree, usually greater. The rare attempts to try any other form of government were unstable and short-lived. The American founders’ idealism lay in their belief that an alternative was possible. Their genius was to design a system with multiple safeguards against the forces that had made previous attempts self-destruct.
America proved that a durable alternative to the natural form of government was possible — a constitutional republic combined with carefully circumscribed democracy. The idea behind that alternative eventually spread around the world, but neither the United States nor any other country that has made it work has ever been out of danger. If we decide that our system for tending the garden needs to be replaced, and if the replacement should prove to be even slightly less devoted to keeping nature at bay, the garden will be reclaimed by jungle within a few decades.
