That's one of the lamest things I've ever heard. Take a look at the results of the previous depressions in history (how did those depressions start? people stopped investing/spending money). How the hell was that a good thing? Sure the economy bounced back up but we don't WANT another depression.
I'm sure half of these protestors will park their BMWs and mercedes on their way to go protest against people spending money. Spending money IS good; against their argument: it's easier to help the planet when we HAVE money

What do you think?
