It is a canard. The anti-tariff crowd is half slicing it and cherry picking. China has built itself from a centrally planning Marxist economy to one of the most powerful economic engine in the world in a mere 30 years, based on some of the most protectionist, mercantilist policies in existence.
Those practices have not hurt them at all.
Oh yes it does hurt them. They are what, 5 times our size - larger by geography and by population, and they can't even garner a GDP equal to ours. Their standard of living is nearly Medieval in inland and rural China.Take Hong Kong (a western creation) off the board and their way is hopeless. Just like socialist Russia, which is another to examine.
They live by way of 3rd-way socialism for their elite business class, leaving the rest to a form of serfdom. This 3rd-way will fail just as bad.
The other half of that slice is that American jobs have bled out the last 30 years since NAFTA as we have always been on the short end of the stick. Even if we have negotiated an equal trade stance, the WTO or whoever is in charge will not punish our counterparts for cheating and skirting the agreement.
All of economics is circular, economic policies work on all directions for and against with winners and losers at every step. There is no half slicing. Tariffs may be rude and crude, but they are the only hammer we have against mercantilist nations. I do not think Trump means them to be permanent, it is up to those nations to decide that, although with China I do believe he is trying to isolate tem on trade.
Doesn't matter - That's the head fake.
The attention is on how other countries treat us and take advantage of us, which is a fair point. It just doesn't matter.
If we truly practiced what WE preach, how other countries treat us would not matter at all, because that roaring economic engine knows no equal - That is proven for decades.
Protectionism is a damnable lie, that shows no light - NO LIGHT - on the systemic problems that are keeping our economic engine throttled down. Those problems are INTERNAL, and by those problems we will fail.
