It's not all horseshit tho tbf. This is from the White House fact sheet:
"Countries including China, Germany, Japan, and South Korea have pursued policies that suppress the domestic consumption power of their own citizens to artificially boost the competitiveness of their export products. Such policies include regressive tax systems, low or unenforced penalties for environmental degradation, and policies intended to suppress worker wages relative to productivity."
This is actually bang on - obviously only raised as a stick to beat these countries with but it's still correct.
Throwing blanket tariffs at everyone obviously still is the most unhinged attempt at butt naked imperialism ever. God bless the orange dickhead for his idiocy, nobody else American or not could have caused as much damage to the US as he has already
