You can't count on Europe and Asia to destroy themselves just to give us a positive trade balance.
Once they got up and running again, by about 1970, we've been running a trade deficit every year (except 1975, which wasn't an especially great year for the economy).
I'm not a free trader, but from what I learned in econ in college, there are reasons to be concerned about tariffs and trade wars. If Cavuto learned the same thing I can understand why he might be concerned.
If the economy booms with tariffs I'd be happy about that, but any time you mess with the economy, there's a potential that things will go wrong.
Please do not worry about tariffs. When properly installed, it will actually strengthen local manufacturing and improve security of the nation in the long run. Only economic dislocations if any, will be short lived. And remember, the leverage is ALWAYS WITH THE COUNTRY WITH TRADE DEFICITS. We stand to gain higher paying new manufacturing jobs, and the exporting countries can do nothing about it.
