Ralph, I would have to write a book to answer this question, but I won't.
It all depends who the Historians decide to blame for the failure. Some of course will blame it on Bush.
Corruption: Our current level of corruption in our government has reached an all time high. Much of the waste is due to corruption and individuals pocketing taxpayer money. We now have a Justice Department and other government run departments such as the FBI who are controlled by a corrupt administration.
Lack of new blood in Congress causes many problems. The good old boy club who have been there for most of their lives now dictate exactly which bills will pass and which will fail. We have two parties as a check and balance system, but in reality they all work together to maximize their own personal agendas and financial gain. These career politicians could care less about what is good for the country.
Our debt keeps rising because we now have around 50% who even pay income taxes. Our entitlement systems make it far to easy, and more profitable in some cases, to just stay unemployed and live off the dole. Our unemployment numbers far exceed the numbers reported by the government.
Our lack of strong leadership has set us back many years and further divided this country in the process. We have lost the respect of many countries throughout the world due to this weak leadership.
Our Military has been decimated to the point we are no longer a big power in the eyes of many countries. They no longer fear killing civilians right here on our own soil because they no longer fear our Military.
I could go on and on but you get the picture.
