I am reading everywhere about corrupt governments, corrupt police, corrupt law, etc.
How can regular people put an end to this?
Do you think there ever going to be a "clean", free of corruption world? People with no financial interests?
I'm sorry to tell you that corruption will be a never ending problem in our society. Even the most advance country in the world, you can find lots of malpractices specially in politics. This is like asking for peace or total cooperation for difference and opposing nation, it won't simply happen.
However, there are ways to fight it and bring those corrupt officials to justice. At least people recognized that this is a universal problem and because corruption erodes our trust in the government.
