The Fourth estate died somewhere between Reagan's first inaugural and Clinton's first inaugural. All we have now are entertainment media required to return a maximum profit on their shareholder's investment.
The Bush administration got away with 935 lies because no one was seriously attempting to inform us. You also must have a electorate that wants to be informed. Afghanistan and Iraq were both popular wars, at their inception, urged on by a population that was insulated from the cost.
http://en.wikipedia.org/wiki/Ownership_society">Bush's Ownership Society that he first mentioned February 20, 2003 in Kennesaw, Georgia that stripped away any control on loans was started for a reason. Convincing Americans that a house was a bank where they could get free money anytime they wanted it kept the majority fat, dumb, and happy and left the Bush Administration to buy a war on a credit card. The military and their families are such a small portion of the population, that most Americans did not feel they had ownership of the war.
The wars Bush initiated have cost about a trillion dollars, all paid for on credit, and we are not even paying the finance charges on that debt.
This is not just the fault of the government, the media, big business, or any other target of our anger. As long as a majority of the American people have no desire to be informed, as long as bread and circuses are provided thanks to the media and McDonalds, nothing will change.
