The economy has grown by 20% since 2003. Tax cuts are a big part of that, because so much money has been invested in new enterprise or in existing small business.
Dont forget the fact that the fed went on interest rate slashing spree post 9/11. With interest rates at .5% its pretty hard for the economy not to grow.
Aha, but it was not accompanied by significant inflation. If keeping rates low came with no side effects, they would always be low.
It's curious, in general, that Clinton was praised for presiding over a good economy but, now that Bush is doing to same, he receives minimal credit. I think Presidents are overrated in terms of their influence on the economy, but what's good for the goose...
