A good article indeed.
Changing the world requires a vision, either totally new, or that disrupts the status qou, i.e, restures the current consitituents.
I remeber from a seminar on Business innovation that businesses usually go like this:
commodities --> Product --> Service --> Experience --> Transformation
There is bank in Bangladesh (Grameen) that is not operating according to usual banking practices, and still profitable. That bank deservers to be put in the Transformation category, as it helped lots of people to change their lives. So, it seems that the real issue is to convince those who have money to start changing their priorities, and not to look for profits only. Unfortunately this is in direct conflict with what capitalism is, at least in these days, where every one is trying to reap the rewards as fast as possible.
