One of the great pleasures of using Uber is talking to drivers about why they have chosen to use the service. Almost to a man (and so far all my drivers have been men) they celebrate being their own boss. They decide when and where they would like to drive and even what model of car they will use.
Their ebullience about Uber is also informed by their previous experiences as employees. Quite a few previously worked for limousine companies and had difficulty getting along with management. One was summarily fired to make way for a nephew of the owner.
Their independence has social and political as well as personal benefits. It is striking in my conversations how aware they are of regulatory threats to their business and of the price of inputs, like insurance. Their knowledge translates into a healthy skepticism of government intervention generally. The political sensibility that comes from being in small business is one of the greatest bulwarks of liberty.
