"You left out the part about turning to fascism." Why do you think people "turn to fascism" in the first place??
Seems to me it is often a combination of dissatisfaction with some problems and a charismatic leader that promises an easy fix (if you only give him a lot of power and allow him to silence the opponents).
Sometimes the original problem isn't fixed at all and may even increase, sometimes it is replaced by more serious problems. But at the beginning it seems like things have improved, because the criticism has been silenced. Later, people who perceive the problems are afraid to speak up.
This may seem like an advice for democracies to avoid letting problems grow too large, otherwise you risk fascism. While solving problems is generally a good advice, it is not necessarily a question of letting a problem grow too large. Sometimes the problem can be relatively small, but the timing is unfortunate and it happens right before the election. It is also a question of whether you have a charismatic wannabe fascist leader who is well prepared at the right moment. Two or three smaller problems appearing at the right moment can bring a disaster that wouldn't happen if those problems appeared a few months apart.
