Yes. Read up on "gentleman scholars" from before the 20th century. An astonishing amount of all our foundational knowledge about the universe comes from wealthy dudes (or with wealthy patrons) exploring science for the sheer hell of it.

And when I say astonishing, I mean it. Almost all the foundations of every field were built this way.

Yes, for the most part they took up "being wealthy" as an occupation and "grifting" as a hobby.
