Democracy has an Achilles Heel. Participation by ordinary people, empowered to vote in elections and referenda, is a plus. Political leaders are compelled, by virtue of the democratic system, to take heed of the people. Policy design, in theory, should be towards a public good and in the national interest, as opposed to say, the interests of an oligarchic group.

Participation is also a downside, for as democracies mature, often settling into a stable two-party system, the people tire of the tricks and postures of politicians, a class who every few years must go cap in hand to them for another term. It is not hard to see how this kind of relationship can lead to cynicism and an increasing playing to crass material or nativist instincts.

It may sound elitist but, in as much as democracy brings out the best in individuals, it also brings out the worst in populations. There is no obligation to develop an informed opinion about an issue before voting, never mind expressing a view. It is fine apparently to have half-formed views based on lies or mistruths, to indulge in fanciful conspiracy theories, to deny facts or promote brazen self-interest.

Perhaps because all systems tend towards disorder (if not persuaded otherwise by renewal) democracy may need an overhaul every generation or so. Complacency can be challenged by well-directed reform.

Below is a link to an excellent article which touches on some of the themes I have raised, though in greater depth and with impressive erudition.
