Answer: The author doesn't use any facts to support such a claim, so it can't be proven.

Fallacies are flaws that decrease the validity of arguments. In this case, the idea that all artists are famous and making millions is a fallacy only stated by the author, without providing any facts to support it. It could be considered a hasty generalization, meaning it makes a broad conclusion on a small sample or without all of the data needed to do so.
