Has anyone notices in fairly recent years, protagonists of novels frequently **SPOILERS BIG TIME**

[raccoon]

end up wealthy, and they weren't when they started out?

For example:

Marcus Didius Falco (Ancient Roman mysteries, by Lindsey Davis.)

Kinsey Milhone (A is for Alibi, etc., mystery series By Sue Grafton.)

Boris and Theo (The Goldfinch by Donna Tartt)

And I feel I must add:
Atlantis, the Disney animated film. (OK, it's a movie, not a book. But the principle is the same.)
