I'm speaking about Bush tax cuts during wartime which broke from 140 years of history under both parties and his "Ownership Society" which encouraged lax lending standards.If you are speaking about the Real Estate meltdown, his tax cuts were NOT the cause. Loose lending, shoddy appraisal system, a Congress led by Barney Frank (D-NY) and their policies of forcing lenders to lend to high risk candidates caused the Real Estate meltdown.
