USA an Oligarchy - but so are many other Countries

An interesting study throws light on how small 'oligarchies' control the levers of power in the United States. Maybe the Oligarchies in other countries are not just the product of superior wealth, they may be based on ideologies, class loyalties or ingrained power structures ossified by badly designed constitutions and electoral systems. But most countries share this: the wish of the ordinary citizens is routinely neglected in favor of small constituencies that gain from favors dished out by those they help to control legislation.
