He may know a thing or two about negotiating, but he doesn’t get economics, cause-and-effect.
Bernie Sanders didn’t win the presidency,
Brief joy, due to hope that a modicum of economic sanity may be retained.
Effect2: hope for social sanity, after the uprising of millennial whiners. (Not Trump’s fault, though)
Trump imposes tarriffs on steel and aluminium
Despair over the spirit of Sanders having entered Trump’s body.
Tarriffs on steel & aluminium.
Local suppliers don’t have to compete on price, because the competition’s price is kept artificially high (it already is higher due to the cost of transportation). So their product will remain needlessly expensive.
This means that users (eg manufacturers of trucks & cars) of steel and aluminium have no choice but to buy expensive inputs, resulting in higher prices of means of transportation, of people that want to go to work, and of goods shipped from factories to stores.
This accumulates and results in more expensive purchases. Add to that, that machines (e.g. agricultural machines) get more expensive on the other side of the chain, and the solution of emigration will present itself to many.
According to the above reasoning, weapons will become more expensive, therefore: so will war. Which will not stop the Fourth Reich. So they will just run up a much worse debt than Obama did: he started out with $6,000,000,000,000 (trillion) and ended with $17 trillion.
This 2.8333 fold increase, (to pay for 8 years of 7 wars) costs the average working age citizen (206,567,603.93200 per approx Feb 2018) https://fred.stlouisfed.org/series/LFWA64TTUSM647S $82,297 plus change. Now, imagine that thanks to the government’s CRA you already lost your home, what are you gonna mortgage to pay off the huge debt that your overlords imposed upon you? Your car? Sure, thanks to the tarriffs, they will get more expensive, so it’ll fetch a higher price, but then where are you going to sleep?
If we take Effect2 as a cause, then its effect will be: increased unemployment, meaning reduced tax income; more people donating more money to charity, to help the countless homeless, thus having less to spend themselves: reducing sales tax income, further empoverishing the US government. Ushering in an era of peace (presumably).
