End Times

The key idea I took away from this is that if there are too many elites or wannabe elites in a country that it is in danger of an explosive revolution. The book laid out a few ways that there can be too many rich people and not enough places for them to exercise their supposed awesomeness for the fawning of those around them, but this is the central premise I remember.

I liked the book well enough, if you are interested in general human trends politically and why now feels like you think the 1850s probably felt in the US, this is a good read.
