Assuming your figures are right, so what? So Mexico doesn’t want its citizens to drive an American car. Big deal. That’s their loss.
Why should we penalize our own citizens by putting a tariff on cars made in Mexico? Instead, let them make cars using cheap labor and let our citizens enjoy the benefits of that cheap labor, i.e., less expensive cars.
Mexicans end up doing the work that can’t be automated easily while American employees end up running robotic assembly lines and getting paid far more than they would if they were just doing the grunt work the Mexicans are doing.
If you do not see the error of your thinking, I question you understanding of fair trade. If you do know that error I question your motive for posting such anti-conservative drivel.
