Or maybe the wonders of free and unregulated market. Costs of production are much lower if you do not need to worry about pollution. If we want to compete we must do the same! Much better than obsolete and quaint tariffs (which could compensate the costs of environment protection). Free market is way of the future.
"Free and unregulated" doesn't mean "completely immune from devastating liability lawsuits."
The only time that a polluter doesn't need to worry is when government's got their back, and that happens all too often in the environment of cash-stuffed cronyism in politics.
