You can say still say we are an agrarian society in the sense that people still need the same amount of food, but far fewer workers are needed to make it. Likewise we will always need products which require a lot of capital to make, but in the future fewer workers will be allocated to these sorts of jobs. The economy is changing primarily because of the internet (and also some other factors). But our laws will not suddenly change overnight. Instead they will gradually change to try to respond how the economy is changing. So all of our capitalist laws will still be in place to allow companies that require a lot of capital. But so much of our economy will be directed toward enterprises that do not require much capital in comparision. Publicly traded corporations will have a smaller piece of the pie. So in this type of economy, could you really call it capitalism?
