You are correct. "Made in America" always meant more in the US than internationally. Many American products are looked at as being inferior, such as cars and beef.
Personally, I don't think a MIA Fender is worth double the price of a MIM or even a MIC. But the fact that it's "Made in America" is important mainly to Americans.
Ask Hank Marvin. Things may have changed but Fender and Gibson are brands with appeal.
