No offense, but from what I understand, as an Italian you should be no stranger to the fun, fun party that is corruption and how it works. But you're making the same basic categorization problem most people make. Politicians aren't people that solve problems. Politicians are people who PRETEND to solve problems, in order to obtain and maintain power, which they use to benefit themselves and their friends. Sometimes they accidentally DO actually solve problems, but that's not their profession, or their intention. You look at that long list, fentanyl, immigration, housing, etc, and you see a bunch of suffering that should be ameliorated. THEY look at it and see a meal ticket, an elevator to the top floor. And when they get there, all those issues will still be festering. They have to get re-elected after all!
It's a cynical way to see it, but it's true, we as a populace have lost the capability to understand who is trustworthy and who is not, politics is not for everyone, we should have a selection of prepared people who know what they are doing, but to discriminate prepared people from inept, you should have a logical mind, but we vote base on sympathy and personal interest. We in Italy have a long, long history of this kind shitty politician, the sad part is the world is slowly (but not so slowly) drifting into "our" direction when it comes to politics. My hope is, at a certain point in time, things will change for the better, who live will see
