I didn’t think you were, I was more saying that the loss of many of those jobs that had been outsourced in the pursuit of cheap stuff means that, even if Trump’s proposed tariffs were effective at bringing those jobs back, it might not matter because they would still cost more than most residents of the US would be able to afford. At least, with current working conditions, many of these goods would simply cost more than people would be willing to pay, as we’ve been collectively conditioned to want as much stuff as possible, as cheap as possible. Domestic production of so many goods would require a drastic shift in consumer habits to even have a chance at being viable in the long term, but they absolutely couldn’t do the sort of volume that places like China has and be able to sell at a profit, barring the implementation of Chinese-style working conditions.
Would probably be more relevant to measure English-speaking countries’ ability to speak whatever the most commonly studied foreign language is, rather than Japanese. That would also probably need a caveat of eliminating native speakers and/or heritage speakers from the data set in some countries, as well.
