A lot of comments are rightfully pointing out the destructive nature of this move. But looking at it from another angle, is it possible this is a symptom of a deeper problem?
What if a significant portion of the electorate no longer believes institutions like the EPA are neutral arbiters of science, but instead see them as political actors pushing an agenda? If that belief is widespread, is an action like this seen not as 'destruction', but as 'dismantling a biased system', even if it seems counterproductive to the rest of us?
One of the most onerous regulation regimes in the USA comes from the FAA.
When people question these regulations, and the cost of certifying aircraft and aircraft parts, someone always rightly responds "these regulations are written in blood."
The same can easily be said about environmental regulations, except in their case, the pool of blood is orders of magnitude deeper.
Do people really think that President Richard Nixon created the EPA to stick it to big business?
Step 1: Point at immigrants/trans/blacks/etc
Step 2: Cut taxes on the rich. <---------- You are here
It works every time. Pres. Lyndon B. Johnson said: “If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you.”
How stupid
It's really depressing how the US system seems to have existed "on belief". Once somebody set out to damage or destroy it, away it went. Pretty much without a whimper.
As I recall, the system was set up with 3 branches of government in tension. Obviously, that was naive.
