Can you be more specific? I am interested in what exactly you think will not work?
The primary issue is that you can't exercise tax cuts while also continuing a policy of deficit spending. The reduction of revenue requires additional borrowing which further drains revenues with additional debt maintenance.
I know the supply siders love to say that tax cuts generate revenues. Only problem is, there is no proof of that because the government, at the same time is also injecting monies into the appropriations stream through borrowing which mimics "growth" without actually providing that growth.
Studies from the 1981 Reagan tax cut show that they negatively impacted the GDP by 3% in the first two years. That sharp decline is why, in the first 13 months Reagan went from TAX CUT to the largest Tax Increase as a percentage of GDP in US History. The deficit spending associated with the tax cuts simply drained the system at a rate that was not expected.
In 1990 Bush 1 experienced the very same issue and the following recession lost him a second term. Bush 2 experienced the very same issue in both 2003 and again in 2006-2008 and provided a catalyst for a Democratic victory in 2008. The three times Supply Side Economics have been tried, and deficit spending have been associated with them they have failed.
The Limbaugh farce, and that is really all it is, comes with a Supply Side/Deficit Spending equation already designed into the system. How many times does the NeoCon mind have to experience the same lesson of failure before they learn to consider a different set of options?
