The average IQ of any country is right around 100, which is far too low to make any beneficial or just decisions about running a country. Democracy is a bad thing. A constitutional republic, sort of like the original US constitution, before it was changed to gave excess power to the public during the Progressive Era, is a very good model. However, the party system, which isn't written into the system, but just sort of evolved, is the downfall of it. It changes it from a system where we vote for the most competent person, to one where we vote for one of two pre-packaged sets of ideologies. That is a total failure, and corrupts all who engage in it. If parties were abolished, and the power to elect senators returned to the state legislatures, and of course something done to neuter the Supreme Court so they stop subverting the power of the legislature and of the Constitution, the US would have the right kind of system.
