Cool strawman. Obviously unlimited losses would ruin anyone but that is impossible and most stores operate well within their expected loss margins, so markups are arbitrary or caused by inflation. Backing up a bit, you are again blaming the more vulnerable group in this. Be mad at the CEOs and politicians that keep people poor, not the poor people trying to survive. Crime drops in direct proportion to drops in poverty

Also, you keep repeating corporate propaganda. It is more common for these companies to use shoplifting as an excuse to close stores that they already intended to close rather than closing them because shoplifting was actually a problem.
