Yes, this article causes endless debates. My opinion: buy whatever car you want to with the money you earned. If you buy a Ford Fusion made in Mexico by exploited cheap labor you can say “the profits stay in the US.” But ask yourself, in that situation, who has those profits? Is it primarily in the hands of the executives (read: the 1%). If you buy a Toyota Camry and are told “all the profits go to Japan” ask yourself (and the questioner) “just how much of every $1 spent on a Camry goes to US workers / US executives / Toyota in Japan and how does that compare with the $1 spent on a Ford fusion made in Mexico?”
I have not come across any numbers in that amount of detail. Also, the profit margins on mass-produced midsize sedans like the Camry are relatively low to begin with. Given that, what precisely are “all the profits going to Japan?” I hear that argument in a Cadillac vs. Lexus debate. It does not make much sense to me in a Mexican assembled Ford Fusion vs. a Kentucky assembled Toyota Camry.
