Flint situation is so visible because generally the gov't does a great job at regulating water quality.

We are not there on greenhouse gas pollution, but the EPA has done some wonderful work on particulate pollution. Also, remember that the old ozone hole is healing? That was helped by a consortium of governments.

"Gov't" can mean so many things. This meme ("the Government can and does fuck up pretty much everything you hire them to do") is inaccurate and heavily influenced by the high profile failures that lead to availability bias.
