As the other answer says, surely this would always be the case. People do not deal with government regularly and there is a strong disincentive to report upon this.

I think you see the same thing in every Western democracy where people believe there is no corruption or believe in rather comical forms of corruption, but the corruption is actually systemic and a function of some political configuration that can't really stand change. This is certainly the case in Germany where you have this odd alliance between unions and billionaires that has basically led to, despite the amazing talent of their people, amazingly poor policy delivery.
