That's a tough question, but a very relevant one for my country right now. In the past few years, Brasil has witnessed the reveal of massive, country-wide (and even international) scandals and corruption schemes across the whole political class. All this and more has resulted in a political crisis we still can't seem to wrap our heads around. Some have become apathetic to politics. Some have turned to radical ideologies, entirely giving up on democracy. A few people genuinely dream of a new military coup like the one in 1964 to "restore order".
I don't have a good answer myself. To be honest, I'm in the apathetic group, but I'm aware that change won't happen if people don't rise to the occasion and demand changes, transparency, and accountability. Democracy tries to put power in the hands of the people, but they need to actually use it.
