The United States does not have the most democratic government, nor is it the least corrupt, nor does it have the freest media:
Index World Rank
Corruptions Perceptions Index 2010 22
Press Freedom Index 2010 20
Democracy Index 2010 17
Demand democracy in the United States. Demand democracy worldwide. The US democracy index doesn't even include the countries that were corrupted the the US.
