Also, just off the top of my head I would expect many people getting life in prison for other things are younger than people getting life in prison for financial crimes, since financial crime tends to happen between mid 30s to mid 40s and violent crime tends to happen in teens and twenties. Assuming that the reason for skewing financial crime higher, because needing business connections and experience to pull off, holds with the size of crime without an stats to back me up I will say my naive expectation is the financial crimes that earn you life in prison would tend to be in the 50s, while the violent crimes mainly remain teens and twenties.

some non-violent offenders definitely need to be put into the same prison as violent ones
