From time to time you see the latest Corruption Perception Index scores come out [1] and the USA always ranks among the least corrupt countries.
That's due to the difficulties in defining corruption. Here in the USA I think there is very little illegal corruption that happens. Very few people avoid a speeding ticket by greasing the palm of a police officer.
Instead we have stuff like this, where a powerful family, aided by the most prestigious management consultants [2] kill and addict millions of citizens, but they took steps to ensure the law accommodated their evil, and protected them afterwards. It's not technically corruption because they worked within the system to pass their laws and peddle their dope.
So then it's not just local police, or a local government, or even one administration that people see is corrupt and working against us, but the entire system of government, 'by the people, for the people' has somehow been perverted, and turned into a sham.
And then these same villains see how the people have no mechanism to fight back, they see all we can do is roll over and take it, and it inspires them to think about what they can get away with next.
