IMHO, 80% of the spending that shouldn't be done was done not by Bush but by representatives those who complain about it a lot elected. Bush stayed afraid that Congress would start to get funny with the money for Iraq and Afghanistan if he pushed back on them too much. Blaming him for what Congress was up to isn't much better the Barry blaming him for the Baawknee Fwank Fannie & Freedie Follies that brought to a crashing close the idiotic policies Carter started and Clinton expanded.

Obama personally sued CitiBank forcing them to give out bad loans.
