If you are familiar with the Laffer curve, then you are aware that tax cuts only increase tax revenue when the taxes are on the right side of the curve. I challenge you to find a statement made by any economists indicating that they believe any of our taxes are on the right hand side of the curve.
Only if you assume that all economic growth is caused by tax cuts. Of course that would be a faulty assumption. If you look at the tax revenue for any year that taxes were cut, you will see a dip in inflation adjusted tax revenues.In fact, every case over the last 60 years, major tax cuts have more than paid for themselves.
So if cutting taxes creates more tax revenue, then why don't we just get rid of all taxes? We would have tons of revenue then wouldn't we?
