Not in the case of a life sentence or a quick under a month type stay, but let’s say you get 1 year in prison, and you are a single adult. What happens if you own a house? Do you have to sell it? How does the mortgage get paid? You have student loans to pay? Cell phone bill (that may seem insignificant)? Credit card bills (assuming you have balances on them)? Do things like this just get put on hold until you are released, or are you required to keep paying somehow while in jail? And if you have no saving for it to come out of, then what?
