I'm very concerned about the US Debt to GDP. Here is the wikipedia page on it:https://en.wikipedia.org/wiki/History_of_the_United_States_public_debt
Here is the main image from it:
Some people say that this U shaped pattern doesn't matter. I'm not one of them.
I strongly disagree with the Trump tax cuts. I do however think the tariffs were a good idea. If the debt is going to be brought down, we need a decade or two of surplus budgets. Currently a surplus budget sounds like a pipe dream. How can lowering taxes help us get to a surplus budget? When the debt was brought down after WWII, we were exploiting the resource of women going to work. There was also better automation. Better automation may help us now, but as far as exploiting human and natural resources, we are fairly tapped out. There is no new frontier to conquer.
