The coastal parts of China are first world economies, but parts of China are still effectively 3rd world. It's silly to claim that Chinese workers make "cheap plastic shit". They make high-end electronics, they make industrial equipment, they build ships, they make aerospace components, they even build orbital launch vehicles, communications satellites, and manned spacecraft. There are plenty of sound, factual criticisms of the Chinese government, economy, industry, culture, etc. without having to make things up.
