It's not the USA that doesn't want your trade, it's the Marmalade Caligula and his Magat followers who have no clue how Economics 101 works. But I do recommend boycotting the American products even though most of them are made elsewhere and not here.
To be fair finding American products is extremely difficult outside of the glut of “American” sweet shops which claim to sell American confectionery but are mostly a front for laundering money.
We don’t really have American cars except for Tesla which no one in Europe is now buying.
If you’re going to import something from the USA, then It’s probably just as cheap to buy from China, South America, Africa, etc.
I think the orange buffoon massively over estimated how much the rest of the world actually buys from the US
And soon we’ll have even more trade from the likes of Canada and Mexico.
You want to add tariffs to European/British goods, go for it. Most of what we make here now tends to be luxury items such as higher end cars, high end fashion etc and as a result you just made it much more “exclusive” which tends to have the effect of driving demand.
I watch a lot of stuff on finance and there was an expert talking about the US and Canada saying you won’t get Canadians to buy US lumber, because Canadian lumber is much better. But if you put a tariff on Canadian lumber, you’ll increase the trade in these products between Canada and Europe but also the US will stop buying good quality lumber and start building with low quality wood, which due to the GOPs anti environmental policies, will run out pretty quick sending the costs sky high
