Maybe
But shipping jobs overseas requires investment over there and American companies were involved. It's not rational to think tax cuts benefitting the rich didn't contribute to that investment. Companies stayed profitable due to Bush's tax cuts and looked for ways to invest those profits. In a normal recession companies focus on cost cutting to weather the storm. It is simply not possible to credit Bush's tax cuts with doing more than the obvious direct effects given the poor performance of the recovery. There may have been external factors but there is plenty of reason to doubt Bush's cuts were well targeted or of maximum efficiency.
