The second chapter of the book just sets up a strawman. It assumes that people elect the "government" because it assumes those elected are more capable than they are and therefore can rule over the masses.
My view of governments is - as the previous tweets suggest - not so. We simply don't have the time to do everything. I don't think my barista or my financial advisor are "better" than me but simply that they have more time to get good at what they do. It is the same thing with my governor.
