corruption is only made worse by angry mobs tearing things down. what is erected afterwards is almost always worse ironically. the only way corruption is reduced is citizens becoming smarter somehow and slowly allowing the elite to get away with less and less bad behaviour while also creating an intelligent incentive structure for the elites as well as everyone else to drive productive, pro-social behaviour. whats going on in most of the world and nepal is the opposite of that

As you stated, one avenue of resolution has the prerequisite that 'citizens become smarter somehow', however that seems unlikely, particularly since the ruling power is actively sabotaging education.
