Please post an empirical econometric study demonstrating a causal link between income tax cuts and higher revenues. Arthur Laffer, the intellectual father of supply side economics never did. Several economists such as Greg Mankiw in fact empirically disproved it.
Correlation is not causality.
The facts are as stated. Sorry.
Nope.
In a recent article in Grant's Interest Rate Observer, Jim Grant noted there have been 11 major tax increases since WWII. In every case, GDP was higher in a year or two. By our logic, tax increases cause the economy to grow.
GDP always grows, whether you raise or lower taxes. It is a product of inflation and economic expansion. Not tax rates. In fact there must be 30 other factors that also effect the outcome of the equation and there is no means to discern causality with so many drivers effecting a singular outcome.
Unless of course you had 1000s of examples to study spanning 1000s of years. Then you might be able to build such a causative claim based on processes of elimination.
