Entrope, your display of ignorance on world economy, the placement of blame, and the defense of the Bush administration is pure political bullshit. This economic downturn, spiraling to god know's where; cannot be blamed on any one person, administration or event. Regardless, of who sits in the Oval Office, or any other elected or non-elected office (Rush Blimpo), the state of the economy would have and will follow a corresponding trajectory. Open the newspaper. Look at the banks worldwide. Watch the unemployment rate. Observe the effect upon governments and public confidence.
To add commentary on "when the clock actually starts on the Obama presidency", is akin to asking at what point the heart surgeon finds him/herself responsible for the smoking, over-weight patient.
Noone knows; not economic experts, not the most successful business leaders, certainly not politicians, and definitely not entertainers and talk show hosts( Bill Maher); what caused this quagmire or what is the most effective way out. The future (attack on the twin towers, Katrina, housing bubble, etc. etc. etc.) cannot be foreseen. Those in power do what they and their staff believe is best.
The economy and world of finances is dictated by such a vast array of inextricable determinants, that making allusion to Obama and the present economy is rife with ignorance and political bias. Why not blame Henry Ford or an Amazonian hatcheting a piece of the forest for today's global weather changes...if they actually exist.
I have no objection to theorists offering thought provoking intimation, but save the you-against-us mentality. This is global...it is real...it ain't going away. Follow this back, as you would any evolving progression. Maybe it was greed, or maybe it was savvy business practice. Maybe it was excessive borrowing, or maybe it was an incredible period of growth. People spend...people build...people are employed. You will be hard pressed to find a period of expansion without consumer involvement.
Drop the Rush bullshit and let's find a way to help those in need, as well as those who fuel the engines.
