I would say that people continue to misunderstand the difference and the relationships between the national economy (unemployment, GDP) and federal fiscal position (budget, deficit). I think the government has a very strong direct effect on the fiscal position, and a rather indirect, slow effect on the economy. And while the economy is currently doing well, it is because 1) it is following the direction it has been for the last six years, 2) it is doing so at the expense of the fiscal position (the tax cut stimulus is stimulating, but at a cost of revenue.) The fact that the economy is doing so well but the fiscal position has gotten worse should be sending off huge, flashing warning signs with blaring sirens. Eventually, the economy will cycle down. There is nothing in the several hundred years of economic history which would suggest otherwise. And when it does, tax revenue will drop.
What's more, not only is the fiscal position deteriorating because of lower revenue, the economic improvement is speeding us along into another major fiscal concern: the interest on the debt. The hot economy will drive the Feds to raise rates to avoid inflation. That increases our interest payments. Trump alluded to this concern in a tweet a few weeks ago. As the debt grows, and the interest on that debt grows. It is projected that in five years the interest on debt will exceed our military spending. Think of whatever irresponsible, bad with money, power-company-going-to-turn-out-their-lights-if-they-don't-make-their-payment friend or relatives. Now realize that we, collectively, as a country, are worse. So get the fuck out of here with gloating about a 3.9 unemployment rate compared to 4.1. I don't give a shit. It's noise. We're like junkies bragging about a high. It isn't sustainable and we're not too big to fail.
