Just like drug offenses are insignificant compared to "small" time white collar crime, small time white collar crime is insignificant compared to what's going on in the financial sector. It brought the world as we know it to the brink of collapse. Some people in the financial sector were stocking up on food, water, fuel and firearms in case society would experience a meltdown. Not only did no one get convicted, but it's back to business as usual.

There seems to be a rule here. The punishment is inversely proportional to the scale of the crime.
