If you somehow published, distributed, translated, and marketed the book yourself then sure, you deserve a billion dollars. However, because you probably didn't do any of those things, just wrote the book (probably had a separate editor as well), you don't.

The second assumption is that people join companies to "increase their value". That may be true for some people on this forum, but most people join companies for a paycheck, because they can't live without income. If no one had to work to live comfortably, I doubt anyone would care about billionaires.
