Thank you for listening to Power Corrupts. We make this show because we think it's important not to make money,

but it does cost money to make episodes. If you want to help us stay editorially independent,

please consider supporting our work in one of two ways.

First, pre-order my new book, Corruptible, Who Gets Power and How It Changes Us,

supporters and get access to exclusive bonus content by going to Patreon.com slash power corrupts.

For just three dollars a month you'll get access to early episodes and at different tiers

you can get bonus content like uncut interviews as well as the possibility of a

Zoom meet and greet with my producer George and myself. If you don't support the

show I'll be forced to bombard you with ads about socks and job recruitment schemes and mortgage websites and nobody wants that.
