And as far as billionaires go, I don't even think Simons gets enough press to really make a distinction on whether or not it's overly positive. Someone else mentioned Gates, which is I think apt. He has cultivated a savior mythos in the press in which he eradicates diseases using his fortune.
Even if you include everything the Simons Foundation does for disease and health research, it's just a drop in the bucket compared to how much positive spin lots of other billionaires get. Off the top of my head, I think even David E. Shaw gets more spotlight than Simons through DESRES and his whole "spurned academic turned superstar" schtick.
All I've ever heard about Shaw is that he runs a modestly successful hedge fund.
Regarding the senate hearings, they were in 2014. Only the banks involved have paid any sort of penalty. In 2016 Simons and Robert Mercer each donated over 25 million to the Democrats and Republicans respectively. So that's not a huge surprise.
Jim Simons is not yet a household name yet like other billionaires, such as most of the ones who've donated at least half-their-wealth.
