My system is clearly the best, and its a shithole of corruption and nepotism. Therefore all other systems must be even corrupter and nepotister, otherwise my system wouldn't be the best Q.E.D.

The opposite. From here:

Some Background: History conditions much of our thinking about our political systems and most Western democracies resemble Rome’s in 60 BC when, as Robin Daverman humorously says, three aristocrats–politician Julius Caesar, military hero Pompey and billionaire Crassus–formed a backroom alliance that dominated the elected senate. The oligarchs ensured that proletarii votes changed nothing and that the masses remained invisible unless they rioted or died in one of the elites’ endless civil wars. Two thousand years later, in Britain’s general election of 1784, the son of the First Earl of Chatham and Hester Grenville, sister of the previous Prime Minister George Grenville, and the son of the First Baron Holland and Lady Caroline Lennox, daughter of Second Duke of Richmond, offered voters offered a choice of dukes. Today, in many European countries (even egalitarian Sweden) ‘democracy’ is a mere veneer over powerful feudal aristocracies that still control their economies. American voters recently watched a former president’s wife competing with a former president’s brother being defeated by a billionaire who installed his daughter and son-in-law in important government positions and ensured that, as John Dewey said, “U.S. politics will remain the shadow cast on society by big business as long as power resides in business for private profit through private control of banking, land and industry, reinforced by command of the press and other means of propaganda”. Most Western politicians are related by marriage or wealth and have, like all hereditary classes, lost sympathy with the broad mass of their fellow citizens to the extent that, as American political scientists Martin Gilens and Benjamin Page found, ‘the preferences of the average American appear to have a near-zero, statistically non-significant impact upon public policy’: Testing Theories of American Politics: Elites, Interest Groups, and Average Citizens
