Seventy-five Percent of US Adults Think US Government Is Corrupt, Gallup

Scandanavian Countries report 30 percent or less think their governments are corrupt. See complete list in article.

[From article]
Three in four Americans (75%) last year perceived corruption as widespread in the country's government. This figure is up from two in three in 2007 (67%) and 2009 (66%).
While the numbers have fluctuated slightly since 2007, the trend has been largely stable since 2010. However, the percentage of U.S. adults who see corruption as pervasive has never been less than a majority in the past decade, which has had no shortage of controversies from the U.S. Justice Department's firings of U.S. attorneys to the IRS scandal.
These figures are higher than some might expect, and while the lack of improvement is somewhat disconcerting, the positive takeaway is that Americans still feel fairly free to criticize their government. This is not the case in some parts of the world. Questions about corruption are so sensitive in some countries that even if Gallup is allowed to ask them, the results may reflect residents' reluctance to disparage their government. This is particularly true in countries where media freedom is restricted.
