For example, if you can get 12 years for shoplifting $40 [1] or life in prison for stealing $153 of video tapes [2] that stands in stark contrast to starting a company with stolen IP and selling it for $680M and getting 2.5 years.
Some people see this as part of a pattern where the justice system, run by upper-middle-class types, is unduly lenient on other upper-middle-class types, or unduly harsh on poor people. They would also point to the likes of Brock Turner who had gone to the same college as the judge sentencing him; and controversial presidential pardons [3] of friends and major donors.
It's not a completely hard-and-fast pattern, of course; Bernie Madoff got a 150 year sentence.
