Why? What would change in those years? I'd bet that he would be still extremely likely to commit fraud or other financial crimes (if presented the opportunity) after he got out. Maybe letting him keep a few billion would entice him to retire early (not sure if that's the most reasonable option).
> then 30 years won't be enough either
But it's not about deterring him. It's about preventing him from doing any more damage to the society and potentially deterring other people from committing the same crime. IMHO this is one sector where draconian sentences might be actually very effective, people in finance tend to be more rational and calculating than average. If you get a to steal a few billion and maybe somehow stash a proportion of that spending 5 years in prison might seem like a reasonable deal, that's pushing it but maybe even 10, not > 30 though.
