Developed nations that have pride make their own items on their own soil. They don’t invite foreigners in to make those items...such as automobiles
If their pride is founded in fact, their products can withstand competition, even benefit from it.
No man, no country, ever benefited by running from the competition.
Your comment is like saying that our athletes are the best and don't need to compete internationally...particularly at the Olympics.
It is challenge (competition) that leads to excellence...not trade prohibition.
