Michael Milken got a raw deal. His actual criminal offenses only resulted in $318K of damages and were largely related to facilitating tax fraud by others. He was a piker compared to SBF. The judge in Milken's case gave him an unusually harsh sentence explicitly as a deterrent to others; I suspect it would have actually been lower under current federal sentencing guidelines.
