Dude. Let me spell this out for you:
Libertarians and far right conservatives have to P-R-E-T-E-N-D that market failures (like pollution) do not exist in order to justify their fantasy of 0 government. Pollution is real. Real people get hurt. Real people lose assets.
The EPA intervened. It worked. GET OVER IT.
Again.... you can say until the end of time, all of your reasons for denying rights to the people. That just makes you a dictator.
Seriously, how do you think Lenin and Stalin came to power? They found 'market failures' as you call them, and justified their taking all rights from the people.
Sure at the start it was to 'fix the problems', but as you gain more and more power, you take away more and more rights.
Same in Cuba with Castro. Same in Venezuela with Hugo Chavez. Same in Germany with Hitler.
Every single one, had a laundry list of reasons they had to take away power from the people. Some of those reasons had some legitimacy to them. There were real problems in every single one of those countries.
But the results were the same. Dictatorship, oppression, and devastation to all the people, whose rights were taken away, in the name of "Real people get hurt."
I've read the history of the EPA. Before they existed many states were creating contracts to deal with the pollution. In fact, nearly all of them were creating their own regulations that worked perfectly for their respective states. They were finding creative and inventive ways to deal with pollution that both provided perfectly good controls, while avoiding undue harm to the companies.
The EPA came in and wiped all that out, ruining good working systems.
I'll give you a perfect example from Germany. Instead of dropping blanket regulations that are neither good for business, nor all that good for the environment, they have done things like incorporated the rivers. So the river itself, is a company. That company, then charges fees based on the usage of the river, and/or is offset by reducing the pollution of the river.
The corporation oversees the testing of the water, and allows the companies flexibility to find the cheapest possible way to reduce pollution, or is willing to pay whatever fees are required so the river corporation can deal with the river.
We don't do that here. Why? Because of the mindless incompetence of the EPA. The EPA isn't interested in saving the environment, or saving the economy, so much as growing and expanding itself, which is why the EPA spend tons of money on research to justify more EPA rules. The EPA has actually directly funded new paper outlets that are favorable to the EPA.
If they spent half as much time doing what they are supposed to be doing, the Flint Mich water fiasco would have never happened. The EPA knew long in advance about the water issue, but didn't do anything about it. They didn't care about that, because they knew they could blame in on Republicans, and Republicans oppose the wasteful EPA.
Better to play politics, because after all, politics is what expands or harms the EPA. Not fixing the environment.
