It is pointless though, it's meaningless to demand change when you have no suggestions of what form that change should take, because without suggestions on what form that change should be, or what benefits you hope to derive from unspecified changes, the entire thing can simply be (and is, in the case of Gx protestors by the vast majority of people) dismissed as whinging.
The situation is made all the worse by many people being involved in these protests after reaping the benefits of the current system...
Bear in mind that no specific reason is necessary. I think for a lot of people it was to express anger at the mass negligent management of the financial system.
