Erm. These are people who are going far out of their way to draw attention to what they believe are serious problems and try to build momentum for broad action to resolve those problems. If you think that's a "joke", not really sure what I can say to you. Similarly, if you think the appropriate response to this is to hand-wave into trying to blame the people who are protesting for the results of, let's face it, massive fraud perpetrated on the world by "certain financial institutions", I have a hard time even beginning to comprehend your worldview.
