Revisionist history, as far as I know. The Bush tax cuts generated decent economic growth, low unemployment, and improving government revenues during the period after they were fully enacted (2004-2006), and that was coming off the dot-com crash and 9/11. The Dem’s took over Congress in 2007, and that’s when things started heading in the other direction, greatly accelerated by the election of Obama and the Dem supermajority in 2008.
You can’t just tinker with marginal rates and call it supply side. Buy every other measure the environment for business got worse under Bush.
I’ve never seen anything indicating causality between the 2007-2009 Pelosi Comgress and the recession. Correlation yes, but not causation.
The recession was caused by the CRA poison pill pushed through by Dems years before and the massive over leveraging of Fannie Mae and Freddie Mac. There was a massive, unsustainable bubble in housing, made worse by It being the sector investors fled to when the dot com bubble popped.
The recession really had little to do, directly, with the Bush tax cuts or whatever level of supply side was in effect when the housing bubble popped. This article is just Monday morning quarterbacking by someone seeking to point fingers and push an ideological agenda.
