By almost any measurable metric the United States is flourishing. And in some areas it isn't just flourishing it is stampeding.
I will grant you that the debt/spending is a huge problem but at least the country as a whole is reaping rewards from it this time. Usually they spend boatloads and we get buptkis out of it (see Obama)
The threat of tariffs and ending trade agreements has even had some positive outcomes so far (Mexico & Canada)
Now I expect you to howl about families split up at the border (while pretending this was new to Trump) and the debt of course but policy wise you got no winning message.
I’ll give you a dry, technocratic answer.
The economy was accelerating before he was elected, particularly in the summer of 2016. Typically, governments tighten fiscal policy when that happens to try to dampen the economy overheating. But Trump did the opposite. He loosened fiscal policy by cutting taxes but not spending. Typically, fiscal policy is loosened when the economy is in recession and trying to recover. What Trump did was pour gasoline on a fire that was already beginning to burn and grow.
That doesn’t mean the tax cuts were a bad thing. I supported them. But what it means is that the economy is experiencing a sugar rush, which will push interest rates higher, and risks the economy landing with a thud, possibly around the next election. The stock prices of the homebuilding companies are telling you that.
The single best thing Trump has done for the economy isn’t tax cuts, however. It’s deregulation.
