Tool making is highly sensitive to labor cost. Every article is a one-off. It can't be automated, often not even duplicated. There are tool and die makers in the USA but if you want to make consumer products you can't afford American tool and die because American tool and die makers want to drive cars and own their own homes. Chinese tool and die makers don't have the same expectations.
