This video seems appropriate given the current economic situation we're all in. This is one of the RSA Animate series from The RSA:

The RSA: an enlightenment organisation committed to finding innovative practical solutions to today’s social challenges. Through its ideas, research and 27,000-strong Fellowship it seeks to understand and enhance human capability so we can close the gap between today’s reality and people’s hopes for a better world.

I first saw one of these videos via TED.com, you can see the series of 14 here: http://comment.rsablogs.org.uk/videos/
