No the EPA has not been the single biggest killer of manufacturing. Lowering the import tariffs has been the single biggest killer of manufacturing.
The EPA may raise the costs, but that doesn't kill an industry. Letting third world countries compete for free when they don't have to play by the same rules does kill industries. Charging U.S. manufacturers more in taxes than we charge foreign producers in tariffs kills industry. Letting communist countries like China use their slave labor rates to undermine our industries kills industries.
“Lowering the import tariffs has been the single biggest killer of manufacturing.”
So, there you have it. Your one answer to everything. You love the over-regulating EPA and you love artificially high prices for consumers. You prefer big government control on both ends, so no one on this thread should be surprised when you espouse support of government dictate over what we want to consume.
