That exists, it's a functioning education system and electorate aware of current events, past history and able to reason logically and impartially, and a viable fourth estate.

The problem is, as Rousseau warned us, elections only function for so long as the voters are able to see and identify efforts to bribe them with their own money (paraphrased).

So the existing system has flaws. Maybe for every stupid thing a politician said there should be a penalty point assigned? Like in driving: in my country 20 penalty points makes you lose the driving license
