Well, I'm not going to go back amd read the exchange but I too have a little bit of experience in Economics ...
I'll just ask this simple question - Are the incentives in this Tax plan greater than the current, as they relate to production of the widespread economy, i.e. are more people goinng to produce more stuff (or the same people produce more stuff) given the new tax law?
Ultimately, this is the only economic question to answer as the construct of greater good is too subjective and impossible to resolve given the variability of human thought ...
No it really is not.
All you just asked really is if this tax bill is a supply side bill. That is it. If it will have some supply side effects. Maybe yes, but so what?
Better questions if it will boast economic growth enough. It will not, the CBO already said this. Plus the sale pitch of supply side cuts is that they are either budget neutral or give more revenue. I mean it seems conservatives can't even get Laffer right. Anyway, reports have come out they will be neither.
On the jobs front, the predictions have been weak too.
Won't boost consumption or aggregate demand so it wont really lead to much investment which in turn will not lead growth
Also is accelerates inequality, which looking at it through just an economic lense, still structurally weakens our economy.
It incentives jobs going overseas that drives down wages and consumption
And since firms are profit maximizers. They will naturally pursue things that help their bottom line and stock price. Especially when they is not sufficient demand or competition to warrant them investing in labor.
So, you're not asking a very good economic question at all. You kinda just deflecting
But at least your not Blco, so apologies for that.
