climate, their retaining of more profit, or the 100% expensing allowed under the new code would be a good time to expand? Or I got a bigger bonus because my customers had more money to buy more of my widgets this year? Or I took some of my Cap Gains that went up because the Co. bought back shares or their price was driven up based on the prospect of retaining more profits?

That's kind of the point. You can't assume the income you want to plug into the old code would be the same if not for the tax cuts. As a matter of fact, you shouldn't assume that, as that would be a stupid assumption. My suggestion is they conservatively estimated the impact of those tax cuts to come to their $1.1T figure. And based on revenues thus far, it seems my suggestion will prove correct. You can argue whether that growth came from tax cuts, other policy moves, or other reasons, but that doesn't make adding $1.1T to the debt any more true.

And the CBO never said the tax cuts would add $1.5T (or 1.1) directly to the debt? Huh? Wasn't that the whole point to their scoring it? And what the absurd claims made as if that were "fact" are all about?
