Let's start the sharing economy: Will Robben at TEDxTilburgUniversity

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

This is actually a PEER TO PEER CAPITALISM, NOT "SHARING". Another model that involves money. "Sharing economy" is just another way to make money and can be exploitative to their volunteers, workers and the present system. The workers have to work several jobs to make enough to survive.
Not relying on your tax money, money from government funded charity organization and money donation from people is the real sustainable movement: unlike some of these models under "sharing economy" that rent something in exchange for your money is just another profitable form of capitalism in disguise. Do some research who they took from to start their business.
