Popehat has touched on this subject (how the media doesn't understand federal sentencing) from time to time.

(Edit: changed "charge" to "offense" since that is a pattern of behavior rather than a crime.)
Many countries don't have life sentences.
(Edit: forgot the "not" in "not convinced".)
(Often "undersentence" means "completely ignore." Unjustly evicting a family from their home is no less destructive than burning it down while they're out, but the former doesn't even seem to be treated as a crime.)
We should be more concerned about fixing the immigration system so our regulations don't give employers like this the leverage to exploit their employees.
