What do we make of the G20 talks?

Reading a blog by Shekhar Kapur "Why the G20 will fail", I couldn't agree more with him.

My thoughts on this are that when the economy recovers in 2 years, will people remember this recession or the lesson from it? They will again start chasing money, wealth and riches at the cost of personal development and improvement of community, environment, etc. The cycle of recession will repeat itself in 7-10 years as it has done in the past.

There is a general lack of Collective wisdom out there. That is why the wise are so rare while fools abound. Not that I am claiming to be wise but the fact remains that vast majority of us measure success in terms of wealth. That is what the whole world is all about - isn't it? Whether free trade or G20 or anything. Even when GreenTech or CleanTech is hot these days, the lines are divided between the true believers and the big corporates. The corporates want to make huge money out of the Wind Energy movement - thats all there is to it.
