So what’s the final outcome? A long prison sentence or a few years hanging out on appeal followed by a few years in a low security federal penitentiary and a long career doing speaking engagements and appearances? Holmes got 9 years, but her actions had severe real world effects on people. Is that the ceiling for SBF?
I feel like for the most part Holmes had theoretical effects on people – tests that were fraudulent, but where an equivalent standard test was done at the same time, and so most likely everything was caught. I think the time she got made sense for the level of fraud, but thankfully I don't think her actions ended up being actively harmful to individuals (other than her employees) in almost all cases.
SBF on the other hand has conducted a significantly larger fraud in monetary terms, and caused many individuals to lose significant amounts of money. In a way I'd say these are bigger real-world effects. I think it's possible to conclude that he had a substantially bigger negative impact on the world than Holmes did, and therefore feels reasonable that his sentence will reflect that.
