You want democracy to work? Give people real choices, not the usual binary bad or more bad. Make them feel like their vote matters for once.
I’m not satisfied with the voting choices either, but I do have some understanding of why they are the way they are. It is a nontrivial systemic issue, and voting populist does not improve that situation.
You seem to see a dichotomy between the politicians that provide voting choices and the rest of the population that votes. I don’t see it that way. The politicians are part of the population, they represent the population. I won’t tell you to go into politics to try to change things, but if you did, then maybe you’ll realize why it’s hard, and that how things are is a function of human nature, of the particular country’s specific political system, and of the world being more complicated than many people recognize.
