This is a very tough issue and I am not sure tariff is the right solution but something needs to be done:
Current world trades are neither balanced nor fair. All countries erect tariffs to protect their agenda and strategic interests. The US does the same but to a much lesser degree. Countries all use taxation to protect their industries and forcing technology transfer as a condition of doing business in their country. For years the USG let them.
Europe started the tech transfer practice, first it was airplane manufacturing. So now the US has cut throat competition with Airbus. Late in the 20th century, it was launch vehicles and satellites, same outcome. Lately it is tech companies, fining them for "unfair" competition to force them to open up.
First Japan now China borrowed the same playbook and improved on it. McDonnell Douglas set up manufacturing in Shanghai to build MD80 in order for China to buy their airplanes. GM had to do joint venture with a Chinese partner, transferred designs and manufacturing knowhow and only then were they allowed to sell cars there. Now the local partner has their own brands to sell.
Some of us are against taxing foreign auto imports because consumers would pay more. I agree, all countries, Europe, China, Japan drop their auto import tariff, then let's have a fair fight.
World trade is good if it is fair with reciprocity, it is win-win. But unfair trade is bad, it creates imbalance among trading partners, a win-lose arrangement. Concentration of wealth comes perhaps because the middle class jobs in the US are gone and only low paying service jobs remain.
I am not a Trump supporter and disagree with many of his domestic and immigration policies. I feel this way because I had first hand experience of some of the trade practices I mentioned. If that upsets you, I apologize.
