Is this really any different than EU applying import duties and VAT? I'm not seeing what the big deal is here.
I believe import duties are similar to tariffs, and open to criticism on the same grounds.
But while VAT is an "honest" sales tax (meaning it's transparent to users), tariffs is a "dishonest" sales tax (consumers don't realize they're being taxed).
The problem is that Trump is telling voters that he is _decreasing_ their taxes, whereas he's actually _increasing_ them.
