What is little appreciated is that although democratic institutions are the best (or least bad) way of governing societies, democracies are particularly vulnerable to being subverted by plutocrats. Ideology may be the softest, gentlest form of power, but it is the key one in democratic societies. The plutocrats can use their wealth to buy mass media, to fund think tanks, and to handsomely reward those social influencers who promote their messages. In other words, they wield enormous power to sway the electorate toward the opinions that promote their interests.
