Comment: Not only is it the gravest, it's ultimately the only real threat to the masses: all other threats stem from this one.
Machiavelli was right. Many things have changed, but what was true then is still true today. Oligarchic appetites are an enormous threat to liberty and freedom. Machiavelli used his writings to try to convince those in power that oligarchic greed needed to be curbed; his critique of oligarchic domination has often been misunderstood.
Comment: Irony of ironies: that bastion of 'liberty and freedom', the U.S., is in reality an oligarchy - the 1%. Just look at the people they support, like puppet president Poroshenko (oligarch, worth $1.3 billion) in Ukraine, and their 'darling martyr for democracy' Khodorkovsky (oligarch, once worth $15 billion) from Russia.
But who are the oligarchs today in our corporatized and financialized world? They are the super-rich and more generally those who command massive concentrations of wealth, even if they do not own it, or even if they own only a fraction of it, such as the individuals in charge of multinational corporations and financial firms.
Comment: And who exactly are these heartless, ruthless, greedy oligarchs? Psychopaths.
