A person, whether rich or poor, can easily lose everything after just a few days in jail. I was so sure I had read an old Supreme Court case in which punishment for a crime shouldn't interfere with a man's livelihood. I just couldn't find it again, until I found a research paper at the George Mason University:
To be sure, with respect to minor offenses, the proportionate penalty could be one that is in accordance with the offense's gravity and leaves the offender with, at a minimum, his livelihood.
It was on page 17 of a 2015ish George Mason University School of Law paper by Craig S. Lerner about the 800 something year-old Magna Carta...ahhh.
