Time to see if white collar crime does the same time as the equivalent value, say, stolen or embezzled by a commoner -- my guess is the former would just get a slap on the wrist while the latter would be locked away for a long time.
Employers benefit from the status quo of our immigration system. When undocumented Americans are afraid to talk to the police about anything, it allows more powerful thugs to treat them as nonhuman entities. If I may put on my tinfoil hat for a moment here, sometimes I even think employers enjoy this state of affairs and actively perpetuate anti-immigration policies with their political clout.
