I have a confession to make. I think John Oliver's "Last Week Tonight" is funny. It's wrong about virtually everything, but it's wrong in an amusing way.
That said, I doubt the host has too much to do with the amount of entertainment I'm getting. He probably just shows up, reads the DNC talking points he's handed, mugs, and leans on his British accent to sell his arrogant attitde. That's, OK, though. Like I said, I think it's done well and ends up being pretty funny. He's certainly better than the seven or eight other people currently doing the same thing.
However, hypocrisy is never far from a rich, left-wing, joke monkey. Ripping on the wealthy is a growth industry, and John Oliver has made a tidy fortune by complaining about the one percent while simultaneously joining their ranks.
