Something similar happened in music.
You could make a living working for the king or the bishop. Then in Mozart's day, you could make a living working for various lords and even the occasional rich merchant. In our lifetime, you could make it by contracting with a secular record label and getting air time lined up on the radio. Now you can take your talent to the masses and get money selling downloads by the millions. The middle men are disappearing. Trump has few middlemen, almost no one he owes favour to except to the crowd. He is crowd-funding his run for the presidency. Political operatives are being downsized.
My new favourite word: Ochlocracy: rule by the masses
