Earlier quoted context omitted.
I'd agree intermediaries aren't really adding anything of value. The problem is however, even in cases when you can produce something as cheaply in the US as in China, a Chinese seller can still beat you on price because they pay less for shipping. And that seems dumb.
When I buy components from china it is often the case that the price plus shipping is less than the shipping alone from a US supplier.
Anything else I consider too risky. In particular, I never order consumer electronics from China (unless I explicitly go for a particular Chinese brand). The crap quality is not worth the price savings.
