I think it's really pretty simple. Some ultra-rich people are fear driven. However they are ultra-rich, so they really don't have much to fear. They have insulated themselves from a lot of dangers to their bodies or lifestyles, they buy one of those survivalist cabinets for each of their homes, etc. Some of them only see one way they can "lose it all", a popular uprising. They look out at the world and really think there ought to be a popular uprising. They, secretly, think things like: "if I was a poor it would be guillotine time for people like me". So they say stupid things out of this fear.
