Tarrifs on Incoming goods into the U.S. won't replace Income Taxes

What Trump is talking about just isn't realistic and what more likely will happen is that he will instead just reduce the taxes of the wealthiest 1% like before while throwing the country into Deficit Spending like he did last time.

Also, tariffs mostly just keep all foreign goods out of the U.S. from literally every country more than anything else. Why this could be problematic is that tariffs are one of the ways wars start between countries historically too.

So, by using too many tariffs on all incoming goods just will more than anything else create more problems between nations and likely create more wars or bad feelings between nations more than anything else.

Isolationism is one of the many causes of wars to begin with worldwide as well.

So, most of what Trump wants to do will tend to cause more wars and people dying and starving worldwide.
