My guess: he blackmailed rich people and then funneled money to intelligence services under the guise of “giving tax advice”.
Having said that, I gotta think Epstein (or really anyone up to this stuff) was pretty good about feeling out who he could victimize and who he could rope into his things ... and who he couldn't / it would be risky to do so. That probably means not revealing too much to folks he could use for his own purposes... but would want to avoid involving in the really dark stuff.
I gotta think folks who are up to this kind of thing at scale are reasonably good at sidestepping potential land mines / folks who might not be down with the darker things he was up to. Thus I get a little skeptical about the idea that anyone associated had to have known all the details.
Epstein also had known ties to multiple intelligence agencies.
> he was told that Epstein "belonged to intelligence", was "above his pay grade," and to "leave it alone".

Why would favors to friends be 'hard to believe'? Favors among friends seems like a pretty predictable human trait.
You're headed down the tinfoil road here I think.
