Look at Canada, where the population is far smaller than America’s, which is one of many variables. There is less demand overall and while Canada relied on the US for numerous imports, America was not subsidizing Canada. A trade deficit is not a subsidy! The US pays for Canadian goods and services with USD, which Canada then reinvests in the US economy. This is how global trade works; it is not a one-way street where Canada simply takes advantage of the US. https://www.armstrongeconomics.com/world-news/world-trade/tariffs-not-reciprocal/
