Congratulations on the Karma.
I've never denied that people can't make a lot of money self-publishing, but if you really think these 200 success stories are anything other than the exception, I would beg to differ.
If you go
here, you'll see that the author suggests roughly 3,000 indie books are making their authors $1,000 a month or more.
The catch is that books aren't authors, and some authors are going to have multiple books on the list, while others are going to make more than that in sales with multiple books that each earn less than $1000 a month but add up to more than that.
Given those facts, I'd be willing to argue that there could easily be as many as 5,000, 10,000, or possibly even more, people making at least $1,000 a month from their self-published books on Amazon.
The problem is that there are at least 2,369,688 ebooks in the Kindle store, and even if each author has at least 10 separate titles to improve the chance, it still works out to about 4% of authors making $1,000 a month.
These are great stories, and there really are no limits to how much a truly successful indie author can make, but the reason these people make the news is because their success is exceptional.
