Sojourner's Kid:

What's is missing from the original article is that a lot of illegal Fuzhou (we call them FJ's for short) people came to this country via human slave trade. They owe over $18K (back in 80's, but today's rate is about $60K+) to these "snakeheads" (that's how the slave traders are referred as) and many who can work to the bone holding multiple jobs may be able to pay off the debt. Those who don't suffer horrible consequences, death, forced prostitution, and the sort.

Check out page 2 of the article ("A Lower Class of Snakehead"), which discusses the career of Cheng Chui Ping (aka Sister Ping), as well as human trafficking/smuggling from Fujian in general.
