We here in the United States we take our legal system and the level of safety that it provides for granted.  If you go to China (or just about anywhere else in the world) and eat at a restaurant, you have no idea if they are feeding you meat contaminated with mad cow disease, because you cannot sue a restaurant that does that type of thing in China (or in most places in the world except the USA).  In the United States, no restaurant owner would take that risk, because they would get the pants sued off of them.
