I'm specifically talking about China. So, no, we have not had the corruption and dangerous foods/products be the majority of our products.
As far as isolationism is concerned, I never said the prevent all imports from everywhere. However, the reigns need to be pulled back once we become a country that is losing their middle class because all of our factories are closed. There is a happy medium on that continuum. It isn't black and white as you are trying to paint it, just for the sake of arguing with me.
