Some people are fundamentally incorruptible.
Some are corruptible but never had the opportunity.
Others have been exposed to corruption so long it is merely part of the job.
Those of us out here in flyover country are astonished to hear about the corruption in the federal bureaucracy. It's the IRS, it's the VA, it's the CDC, it's the Census Bureau. Is it everywhere? Notice that those who used "conspiracy theory" as a way to demean an idea have gone silent. It's no longer a theory but a possibility that can't be easily dismissed.
The movie "Serpico" was on a cable channel the other night, and in that movie an honest cop is transferred to a division corrupted through and through. The problem is he's the only detective in the unit who won't take the money. He becomes a pariah. It took a tremendous amount of courage to stick to his guns under such duress from his peers. And that courage is what sets him apart from the ordinary person.
One suspects that the typical bureaucrat doesn't have that kind of courage, especially in an environment where the inspector general force has been gutted.
At this point it's reasonable to believe that where there's an incentive in the federal government to meet numbers or to satisfy high profile Democrats then there will be corruption. As for a fix, a top to bottom overhaul might do it. But with the political clout of the bureaucracy and a natural resistance to outside scrutiny that seems difficult. We have arrived in Venezuela.
But there's always hope. Perhaps some conservative/libertarian leader will come alone who, like Obama, will sweep people off their feet, but who, unlike Obama, will sweep the rot away.
