"Save/Change" OR "Leave/Destroy" THE SYSTEM?

I really tried to see some small hope or a spot of light for the future, but I always get slapped around the head when doing so.

Now I have this moral dilemma when aksing myself: what is the right thing to do?
Should we really try to make a change? Is it really possible? When it comes to people who suck the list just never ends - Now what?
Or should we push this shit to the edge and watch it fall?
Because when the overall system becomes so complex that you need to use all your energy and resources just to maintain it, it takes just a small push and the whole system collapses. Now we currently have this famous global financial crisis going on which is really just another way of saying "shit, we're losing money because the system dosen't work any more", when it's actually the result of more than one crisis kicking together, but the "money losing" simply hurts the most.

That is why personally, I'm more in favour of destroying the system, because I think everyone should learn a fucking lesson. I mean we had world wars and shit like that and still people are willing to do this things! People need to see that they just can't go around and fuck up everything. Mass production, overpopulation, pollution, wars, buy this, buy that... al sorts of this shit just can't work together. Humanity has made some seriuos mistakes and looks like it's time to pay & learn from then, even if it's the ugly way of learning.
Damn!

Yeah I know it sounds selfish of me, but really, what sould we stick to? -This is my question of opinion.
