Well, we can see how the prez carefully studied the changing economic climate before and during his tenure, and modified his economic policies to best promote national prosperity in view of the radically changing economic climate.
During the campaign for the election in 2000 there were serious worries that the government was running an unreasonable large budget surplus. The Bush team, somewhat reasonably proposed that a significant tax cut would be a fair way to return this money to the American consumer.
When, by 2001, it was obvious that the predicted surpluses were not going to materialise as anticipated, the same tax cuts were proposed as a means to help the economy to quickly rebound out of recession, in accordance with demand-side theory, by giving Americans more money to spend.
However, the rationale for later tax cuts was rather different - by 2003 it would seem that, despite their failure to stimulate short-term growth and job creation, the tax cutes would, in true supply-side style, lead to long-term growth.
So we can see that, contrary to the theory that a government should be responsive to the changing economic climate and tailor its policies to responsibly offset that climate in a way that is favorable to both business and consumer, the Bush team had a policy that they wished to push
no matter what the economic circumstances were.
Rather like a quack physician selling his own brand of snake-oil, the Bush economic team have prescribed
exactly the same medicine (i.e. the one that most financially benefits themselves and their core source of funding), for three completely different maladies.
This fact alone makes me deeply suspicious of the motives behind the Bush team's economic policies - their justifcations resemble pseudo-science in a way that triggers my bullsh*t detector.
An honest appraisal would probably conclude that the tax-cuts were a result of a 'Starve the beast' philosophy (a defensible concept), but one that has been followed through stealth and flim-flammery rather than an honest and up-front admission.
This Paul Krugman essay puts the whole thing into perspective rather better than my words here.
