Maybe technology, and a little behavioral modification, can help. For example, you can make an agreement with yourself: along with any online statement about endemic corruption, bad luck, lack of accountability, I will do something to reverse this trend I do not like. I will post the names of the politicians, businesses, consultants, responsible for a specific bad outcome. I think that would both strengthen your message and make you feel less helpless.
On a meta-level I'd also be very interested, how many people actually now about corruption of the smallest governing body where they live (and can name some members which got voted in). Given the fleeting lifestyle propagated here and by American laws (hey, there's another job, let's move), it's no wonder the government is captured by landed elites. It's the peoples job to change that and yes, settling down somewhere helps.
