He is saying that such a high price is ridiculous for a sweatshirt made in China. The point isn't about the (guessed) quality of the item but MIC is inherently lower cost than made in high costa countries. I don't think I need to post a chart showing the average factory wages in China vs US to make that point.
The discussion of cost/price in relation to wherever it is made is relevant. It is not "anti-China" to state that a product that's MIC would be expected to be lower price than one made in a higher labor cost country - all else being equal.
