I'm not sure his income was as you described it.
Not just you, but a lot of people ITT are saying similar things suggesting his wealth is legitimate, despite now knowing that he is a child sex trafficker. Once someone stoops that low, all bets are off. From that point forward, claiming "he got his money from a hedge fund" is the far more extraordinary claim.
>a man that was convicted of earning money from sexually exploiting children
That is a pretty specific thing. I don't think it is a"benefit of the doubt" to say that no such conviction exists.
There have been accusations that he got his start by embezzling from Wexner, but as far as anyone can tell so far, the bulk of Epstein's wealth is "legitimate".
It's just a bit too "made for TV movie". This story is under a microscope. If there was a conspiracy that elaborate, it would have come out by now.
I could be proven wrong, but I'm betting on "rich creep who thinks he can buy everything" rather than secret-society mastermind pulling puppet-strings.

That article can be summarized as: "We don't know where he got his money from, therefore let's speculate". It's good entertainment, but reality is usually pretty mundane. It's easier to believe Hoffenberg's claim that Epstein made off with the proceeds of the Tower Financial ponzi scheme. But that too seems heavily investigated already.
OK, how did he earn it? He didn't invest anywhere despite his claims to be running a hedge fund. Most of his assets were transfers from Wexler, or donations from leveraged associates laundered through charities. I've not seen any path through which he had any legitimate income or earnings at all.
It'd be an even worse look if MIT was directly using money earned from child abuse.
