Humans have a powerful need to affix blame and punish individuals. On the internet, you are forever the worst moment of your life.
We set air traffic controllers up to fail, and then when something goes wrong we torture them until they die, and then torture their memory after they die.
Pretty easy!
It doesn't serve us well to act like this administration is anything other than extremely aberrational.
But scapegoating any single politician for the systemic problems of aviation is as unhelpful as scapegoating the controller for the crash at Laguardia.
Is it still an aberration the second time 'round?

Deciding to change policies to effect the recommendation isn't their role. That's why you will so often see a safety investigatory body repeatedly recommend the same thing. The UK's RAIB (which is for Rail investigations) for example will often call out why a fatal accident they've investigated wouldn't have happened if the regulator had implemented some prior recommendation, either one they're slow walking or have rejected.
The investigators don't need to care about other factors. Are melons too expensive? Not their problem. Only unfriendly countries grow melons? Not their problem. They only need to care about recommending things that would prevent future harm which is their purpose.
And if it was the role of investigators to change policy, then there would be enormous pressure from industry to reach convenient conclusions, poisoning the investigation process.
