Thoughts on white-collar crime

Rogue US insider trader fined record $92.8m
We need more of these busts. But how is it that smaller time white collar criminals are often let off without so much as a slap on the wrist?
How did it come to be that white-collar crime is not considered as much of a violation as physical violence?
Betraying trust by stealing someone’s money can have a devastating and traumatic effect on a victim’s psyche not to mention their financial security.
Thoughts anyone?
