You can regularly find the 'exact' same thing on Taobao 10 or 20 times cheaper than what it's sold in the U.S. On one hand, there's an aspect of "Quality". The manufacturing process has defects. Dangerous for batteries, not so much for a pot.
Though... without the price premium, many businesses prolly cannot make ends meet. The 10-20 price difference doesn't point at exploitation but that of inefficiency. Like an obese runner getting winded and needing a bicycle to keep up with someone more efficient.
