Quality...

I believe your incorrect about several things here. American product quality did not win the war. Using Airstream as an example doesn't make any sense in that discussion.

The massive supply chain of goods, higher skills, and luck won the war. The Japanese Zeros as an aircraft were superior in almost every way to the American built, heavier aircraft. The only thing that let the American pilots prevail were there superior skill levels of air to air combat.

I doubt whether we'd still be speaking Japanese, as Germany was the leading Axis Country.

FWIW, the supply chain of goods used in the American cars and trucks are heavily foreign based origin as well.

Do you read what you write? You just supported the position that Airstream quality won the war for America. As you said, both sides had airplanes, and tanks, ships, submarines, guns, cannons, military personnel, supply lines, etc. But Japan lost WWII, the first war they lost in 1800 years! So what did the Americans have that the Japanese did not (besides an atom bomb)? Yup, you guessed it-- Airstream trailer quality in everything we did. 'Airstream quality' won the war for us. I am confident that you, too, can get and maintain an Airstream quality 'Ahh Haa' moment, if you think on what you wrote. And that same quality was evident in supply line issues, resource allocations, military personnel skill levels that you cited, etc. It was everywhere then; today it is rare in RV products.

As to your assertion about a global economy today, that was outside the scope of my original comments about WWII. Yes, today we have a global economy. And most of the RVs built in Europe and Australia are better built than most American RV products. Times have changed.
