The document discusses several key reasons for why Chinese products are so cheap:
1. Labor costs are much lower in China due to large pools of cheap, unskilled labor. Chinese workers may earn only $5 per day compared to US minimum wages of $7-8 per hour.
2. Materials and production costs are also lower since China produces many goods domestically using mass production methods.
3. Some economists argue that China artificially deflates the value of its currency, the yuan, making Chinese exports appear cheaper than they otherwise would be.
