You would never hitchhike, right? A free ride from a stranger? That's just crazy. But you don’t mind paying a stranger to drive you, or let you stay in his house, so long as he has four stars or above. The crowd-sharing economy is helping to redefine what trust means for millennials and beyond. Even if you aren’t in a crowd-sharing business, it’s worth thinking about how this evolution will affect you.
