The evidence is now incontrovertible: the Trump tax rate cuts of 2017 that CTUP cofounders Larry Kudlow, Arthur Laffer, and Steve Moore helped design with the help of Kevin Hassett RAISED revenues over the last five years.

The latest Congressional Budget Office Report shows $4.9 trillion of federal revenue collected last year – nearly $500 billion higher than their projection. And corporate income taxes beat CBO’s projection by 25 percent.

Since the Trump tax rate cuts, revenues are up – Ready for this? – almost $1.5 trillion. That was roughly a 40% rise in revenues in five years. So much for this being a tax giveaway for the rich.

We compared these numbers with the estimates of what the Trump tax cuts were expected to “cost.”   Instead of a $1 trillion “loss,” the tax receipts surged.

In other words, there was a giant Laffer curve effect of higher growth and higher tax payments with lower tax rates.

None of this seems to matter to the Democrats. They want to monomaniacally repeal a tax cut that worked.
