First, BOTH parties are to blame but some of the first mechanisms started with a Republican President even before Reagan.
From Market Watch:
Ronald Reagan's director of the Office of Management and Budget, David Stockman, explained the reasons in a July 2010 Op-Ed piece entitled "Four Deformations of the Apocalypse" It was published almost a year before the debt ceiling bill gridlock caused the S&P downgrade. Article
For the many S-L-O-W guys who post here in the Sandbox, you may have to read it two or three times but the explanation has no holes. It ALSO blames Democrats and "Democratic Capitalism" and might just help you kick the idea that Fox and the Tea Terrorists are telling you anything close to the truth.
Maybe it will even cure the simplistic "Obamcare" [sic], "Big Spending Liberals" and "Barney Frank conspired with Fannie and Freddie to do it" excuses you MAROONS repeat from your agenda-laden "sources" on AM Hate Radio and the rest of the Tea Terrorist Noise Machine.
Republican Stockman's Op-Ed piece also contained this paragraph: "If there were such a thing as Chapter 11 for politicians, the Republican push to extend the unaffordable Bush tax cuts would amount to a bankruptcy filing. The nation's public debt ... will soon reach $18 trillion." It screams "out for austerity and sacrifice." But instead, the GOP insists "that the nation's wealthiest taxpayers be spared even a three-percentage-point rate increase."

Do your research and quit parroting the talking points you hear listening to Talk Radio and watching Fox News! You can thank me later when you're part of the solution rather than part of the problem.
