Hey - guess what? Each inflection point in the curves is a budget year! Guess where the last one ends - 2009... Of course, that’s wrongly attributed to President Bush.
Oh, he was President all right, but he didn’t write or sign that budget that was passed for FY2009. So the Bush years stop at that -$459B mark...
Now do you see it? Or is your ego and blind obedience to some sort of twisted logic all that drives you?
