For decades America imposed a tariff of 2.5% on autos from the EU, including the UK. While the EU and the UK imposed a tariff of 10% on US made vehicles. The impact of those tariffs can be seen in the percentage of US made cars sold in Europe vs what Europe sells in America. It's not even close. It has been a similar situation in the auto sector with countries in the Far East, led by Japan.
That sounds a lot to me like the US underwrote the European, British and Asian car industry......for decades!!! Seems pretty odd to me that people would be upset about a re-balancing of that disparity.
And it's not just the auto sector. This kind of disparity has existed between the US and the rest of the world on a massive amount of trade, from raw materials to finished goods. The US has been giving it away since WWII
