>> "heaps of 20$ bills lying all over the place" This isn't the case from my experience. I've networked with and interviewed dozens of people. It's incredibly difficult to find worthwhile problems that can be automated and aren't already automated. And, even here in the bay area, people tend to react pretty negatively the moment you even mention "repetitive processes". No one likes automation: they associate it with getting fired. So, if you ask people about this, they tend to clam up and stop talking pretty quickly.

And when you get right down to it, and start having the type of deep dive talks need to have with potential customers, you'll quickly discover there's already solutions to almost every conceivable problem out there, even in the some of the most esoteric fields you can imagine.
