If Trump goes through with his wide-sweeping tariffs, there will be trade wars. That goes for tech, too.
And keep in mind, if he installs nothing but loyalists and sycophants, who's to stop him from these half-baked ideas?
Are you aware of the tariffs other countries have?
Try importing California wine into France or Spain as an example. Try importing American cars into China or South Korea.
There is also the de facto tariffs from Chinese currency manipulation.
Hard to be intellectually honest about tariffs without looking what much of the rest of the world already does.
Tariffs can work well. Sometimes you want to have tariffs, depending on the functionalities and industries you want to keep domestic.
But imposing all-encompassing tariffs is just plain nonsense. It is dangerous nonsense. Replacing federal taxes with those tariffs is even worse.
Again, Trump is fixated with tariffs. At least his idea of it. The last time he tried, ask farmers how that went.
