Of course they have. That's the name of the game. Either they are corrupt, in which case the citizenry will get rid of them, or they are doing what the majority want, in which case they will stay. You will never get 100% consensus, that's why we have various forms of democracy. Some are better in some circumstances than others. Ultimately it is up to the electorate to persuade enough people to keep or change.
Whilst you may be right about many things it is as well to look at the possible alternatives.
I hate to say this, because I am sure that it goes against every red corpuscle in your body, but a totalitarian system such as that practised in China is, in some respects, better than the democracies we have been playing with for years. They have progressed more in the last 60 years than Europe or the US. granted they started from a lot further back but it is the US that owes China money not the other way round.
