"Buy US or Else" bumper sticker = Nice life there, wouldn't want anything to 'APPEN to it, would we?

Living in the eastern part of Michigan, I see a lot of bumper stickers advising me that I am one of many, or perhaps all, types of bad people unless whenever I buy a car it is "made in the US."  That's been true throughout my life, and in the past I would just ignore it.  My father worked at Fords, and his take on it was that many of the big three ran factories in multiple countries and if you bought a Ford it was likely to say "hecho en Mexico" or "fabrique au Canada" on it.  I found out he was right: I've owned 2 new and 2 slightly used Fords; of them, one was made in Mexico and one in Canada.  Conversely, at that time (late 80s, early 90s) Toyota, Honda and Mitsubishi employed a lot of Americans....which is important to know because of course the "buy American" crowd sincerely believe that if you buy a car made by a foreign company, you are personally responsible  for the high unemployment rate.  But since the Japanese companies employ a lot of Americans, if you buy a Honda Civic or whatever, you will help them maintain their jobs.
