The Big Society requires a significant culture change, from one where people turn to officials and government for answers to the challenges they face, to one where they feel empowered and equipped to help themselves and their own communities. Writer and social innovator Rachel Botsman argues that just such a shift can be seen in the growth of 'collaborative consumption' - an emerging culture and economy of sharing, swapping and trading that is transforming how and what we consume. Fuelled by a mix of drivers including the rise of new technologies and social media, a rethinking of traditional market principles and a renewed belief in community, many more people are now sharing not just material goods, but also experiences, skills and time. Join Rachel Botsman at the RSA to find out how the millions of small contributions that make up collaborative consumption are accumulating to create a new kind of wealth, where commerce and community meet.
