Not quite what the article was talking about, but what worries me about modern democracies is where the responsibility of government decisions lies. In theory the voters should bear it, since they chose the government. But in practice they just shrug "rotten politicians" and move on with their lives as their country wages war on millions of innocents. The politicians themselves rarely get their comeuppance, because hey, the people chose them!
Democracy only works with a politically active population. And frankly, most people don't give a shit.
