Do you think the US plays by free trade?
Intellectual property rights/copyright laws, both linchpins of US policy, are the very definition of government intervention.
The US aerospace and manufacturing industry is overwhelmingly subsidized by the military complex, a lot of it done under the auspices of "national security". For the US to complain about Airbus or Bombardier is simply incredible.
US agriculture is outrageously subsidized. I'll go into a specific example in a moment, but the notion that that the US is trying to play fair is simply incredible.
The US loses at the US-created WTO time and time again (see: Canadian softwood) and simply ignores the rulings.
"but when your "allies" have had non reciprocal tariffs"
I don't know what example you're thinking of, but let's consider the case of Canada (a country that the US has a trade surplus with). Canada has supply management for dairy to ensure a supply that matches demand to ensure food security. To protect this, Canada applies a high tariff for imports above the quota.
"So unfair to US farmers!" yells Trump.
Only here's the problem with his ignorant, easily swayed vision.
Canada exports less dairy to the US than vice versa. Like, 1/2 as much. The whole point of supply management is that it doesn't generate an excess, and for that small industry the exports and imports are generally only for very specialized things.
US dairy, in contrast, is hugely subsidized. To the tune of 74% of US dairy income comes, directly and indirectly, from the US government (0% in Canada comes from the government). Hence US farmers grossly overproduce and then look to dump it elsewhere, destroying production elsewhere. Just as US corn production is essentially a government enterprise, flooding the world with corn by-products and HFCSs.
Who is the villain here? Trump can rattle off some scary number to his clueless fans (I'd steer clear of the pejoratives, but given that Trump is a lifetime grifter and con man, whose virtually every statement is an outrageous lie, it is incredible that someone can be called his fan), but Canada has nothing at all, whatsoever, to do with those poor American farmers. It certainly isn't Canadian milk on American shelves causing their ills, because Canadian milk isn't on their shelves.
Nor did China cause the US poor to live in such dire straights. This is just the latest example of the US becoming more and more polarized, while convincing the poorest that it's always some external reason why they live in destitution in the richest nation on Earth.
