ipads and their real makers'

i read the article in china human cost are built into an ipad. in the article of human cost being built into the ipad's their telling about the dangers the workers, face and the majority of accidents that the workers face. from the way i was told the factories aren't dangerous or hazardous to the workers,they don't even tell about the long hours they work. supposedly a safe and secure working facility for workers, how many other times were we lied to about what's really going on.
