This is true of most strict rules elsewhere: they're there but seldom enforced. Take speed limits, they're strict, but good luck enforcing them. All we do is we monitor from time to time and give tickets. Yet we could enforce this to the manufacturers, right? Why can a car go beyond the speed limit if it's strictly prohibited?

We cannot compare working conditions as is, but they're easy to compare when you take time into account: how where our labor laws a couple of generations ago? Not that different than poor countries today.
