You are missing the big
You are missing the big picture. Yes some Toyotas, BMWs and other foreign cars are assembled here. But the US employment numbers paint a very different picture than what you're trying to say. Are you intentionally misleading people? Or are you just misinformed?
Here's some job numbers for you:
GM employs 77,000 Americans
Ford employs 65,000 Americans
Chrysler employs 39,200 Americans
Toyota 30,000 Americans
Honda 26,000 Americans
Nissan 10,380 Americans
Hyundai-Kia 7,800 Americans
The Detroit Three employ two out of every three autoworkers in the U.S.
Also, if you buy an import brand even one assembled in the US, most of the white collar jobs we send our kids to college to get (design, engineering, finance, management, ect ) are overseas. All the taxes on those salaries and any profit the companies make are paid to other countries. So we get high taxes, bad roads and lousy schools. Is this what you want?.... I certainly don't.
Buy American the job you save could be your own!
