Great question. There's no insightful answer I can give that would solve all of this. The only peaceful move for change I can see for millennials is to wait out the current leaders into retirement and take their places. However, that's only effective if the replacements aren't corrupt themselves. Once millennials are the majority in government and business, they will have their peak opportunity to turn things around, or fail miserably. Until then, I don't see other options besides violence to turn things around while they're still in somewhat fighting age range. That's not the route most would want I'd imagine.
