It isn't that simple. The punishments are actually rather sever for most people. What is different today is the power of extreme wealth to nullify or rationalize harsh punishments. I would say our current system of equal punishment for equal crimes might need to be updated. Punishment could be somehow tied to personal wealth, as speeding tickets in some countries are based on a percentage of one's income. For cases like Holmes', perhaps garnish her income, say 80% of everything over 100k/year, until she has repaid all debtors twice over. (Actually take the money, allow no bankruptcy escapes.)
