THE TAYLOR
In my opinion the taylor was the only sympathetic character, he just tryed to make a honest living and provide for his (poor)family, even if he was making some side money working for the chinese. I guess in the end he managed to come out clean with a new job and while we see him at the restroom with other workers on end of shift, we can presume that the truck he was driving was in fact his own, bought with the money he earned upfront teaching in the chinese warehouse. Most likely he would than be hired by the crooked rich guy to deliver the toxic waste but he is working by himself.
