Your source says there are currently 5 billion internet users, that's the vast majority of people.

Of course there are still factories and farms but people are not limited to those vocations, in fact no one is limited to any vocation! That's why they idea of class warfare is silly in the United States, in other societies there are actual fixed castes and you can't really transition between them. Here in America anyone can be anything they want to be, you don't have to be born to a royal family to own land or be an aristocrat to form a corporation. An untouchable can come here from India and become a wealthy scientist and inventor. Most Americans occupy different socio-economic strata over the course of their lifetimes. There are no fixed classes so that makes class warfare ideas even sillier.
