Are there other societies you have in mind where wage theft is a criminal offense? It seems to me that the difference in punishment is because of the mechanism of the theft, not a judgment that the underlying fiscal harm doesn't matter.

I do know that other countries don’t incarcerate anywhere close to as many of its citizens as the US, especially for what amounts to a rounding-error’s worth financial loss due to petty theft (a handful of fighter jets worth).
