There are lot of people not entirely happy with the current economic system and the inequities that it causes.  Different people are trying out different alternatives and ways of living that get around some of these issues.  The video below is not how I would want to live.  I envisage being able to exchange with people in a fair, compassionate way while still working at normal jobs, living in normal houses and so on.  But I understand and respect the thought processes and sentiment behind people trying this sort of thing out.
