I think that its most likely that Epstein blackmailed to riches.The strangest thing is how a high school teacher could become a billionaire financier in a few years with no footprint in the finance industry.
My only guess is that he was pimping for the rich and famous and in a position to blackmail his clientele unless they set him up in business.
The story coming out about Wexner and Epstein shows Wexner gave Epstein $200 million over the years and power of attorney and nobody knows why.

Wonder how much other dirt Epstein has up his sleeves, like Acosta's work letting him off easy previously.
