Critical thinking
It's not disagreeing with Bush comment, it's failing to offer a basis for it. Clearly you are an able thinker. Critical thinking and thinking are two different things. Good news - critical thinking skills are largely a purposefully acquired ability, though admittedly not very widely practiced. Developing them and using them, doesn't make me or anyone else arrogant, just better informed by having a factual basis for an opinion.
The housing inflation, credit default swap/mortgage bundling scams and the economic crisis under the Bush administration as demonstrated by house price inflation 2000-2007 isn't really debatable. It's demonstrable historical and mathematical fact now. We can point to many other minor extenuating factors from previous administrations - but nothing takes the responsibility and or the cause-and-affect of the housing bubble timing from the Bush administration. Bush was responsible for the collapse. For the recovery - Bush a little, and Obama timeline wise - is more responsible for any subsequent recovery (or not) - if there is going to be a sustained one. Frankly, the lack of real job growth, significant manufacturing increases, or increases in manufacturing product diversity and lack of motivation to encourage business in the US under Obama makes me highly doubtful of his administration abilities to produce a sustained recovery. I see little difference between Obama and Bush - other than they are/were owned by some different corporate interests. Bush - oil and defense and Obama health care and defense.
