They have no labor unions.
They have few or no environmental regulations.
They pay little or no attention to international patents, trademarks, and copyrights.
They pay next to nothing for employee health care.
They have an educated work force (See news stories about how Shanghai students were #1 and the US was below average in an international test of high school students)

My wife is from Mexico, and she told me that many "crafts" traditionally made by Mexican Indians are now made in China. That will give you an idea about how cheap Chinese stuff can be.

The Chinese government is against freedom of expression and supports dictatorships like North Korea.

It's all kind of scary.

I do not know about the feasibility of boycotting Chinese. Something must be done about allowing the Chinese to compete freely when they have no labor or environmental laws and allow piracy to run rampant.
