Indeed
"Tax cuts thus almost never pay for themselves in full."

For a tax revenue to remain neutral with a tax cut, the economy has to increase in size at a commensurate rate... And that just doesn't fucking happen, the economy does not grow that fast.
Not to mention that getting back to the same revenue doesn't even help at that point because federal outlays increase as the economy does.
