He wrote a book!!! That's what all the socialists say when it's suddenly discovered they are, in fact, multi-millionaires like the people they rail against. Of course they aren't giving that up, but you'll give up yours.
First, it was the people that made hundreds of thousands of dollars, and when the socialist started making that much then it was the millionaires. When they started making millions then they started complaining about the multi-millionaires. When they themselves became the multi-millionaire, then it became about the billionaires.
Socialists always go after those who are making more than them.
