Krugman, again:
"If you ask how it’s possible that a handful of bad actors can get their way so often, the answer has to be, wasn’t it ever thus? What we call civilization has usually been a form of kleptocracy, varying mainly in its efficiency (the Romans were no nicer than the barbarians, just more orderly). Yes, we’ve had a few generations of government somewhat of, by, for the people in some places — but that’s an outlier in the broader sweep of things. So never mind the hive-minds; good old greed still rules."
