The really funny part about all this trade war talk (or worse, actual trade wars) is that they actually do nothing to "protect" the people employed by these various industries. The people working for these companies will still have to pay more for literally everything. Tariffs work both ways and these companies will retaliate.
Idiots like Trump and Bernie Sanders think that trade is a zero-sum game. There is something called opportunity cost to produce any one product, and those opportunity costs are different for each nation. It is more efficient for each nation to produce the things which have the lowest opportunity cost and then trade those items with other nations which will in turn produce other items.
These retards, exemplified by the Bernie Bros and people like spaghetti-monster above, are so stupid they don't understand basic macroeconomic principles like opportunity cost, so they fantasize about "protectionist" trade policies. Luckily, until now, America has been smart enough to never give these imbeciles any job of importance, so their ignorant fantasies were just that - stories read about in books. Now that we have the ultimate retard in charge of the country, these policies can become reality!
