An interesting short film from the RSA about what really drives people and motivates them to do good jobs. It turns out that what motivates us is less the prospect of profit and more chance to make a difference. That finding challenges a lot of the preconceptions of both capitalists and socialists, although it has to be said that for menial tasks it turns out there is a profit motive. So, we should be giving factory workers financial incentives (and should be taxing demerit goods) but shouldn't be rewarding managers in a similar way.
I'm increasingly finding linkages between the various social benefits that come along with reducing inequality and the creative commons/open source culture. It looks like a path worth exploring in more detail.
