> if you don't have a job, so being put in jail won't make you lose your job, you should be jailed longer to make up for the fact that jail harms you less.

I know you were being facetious but, due to how the US legal system works, if you don't have a job/income, you likely have worse legal representation, which means you get a worse plea deal, and do go to jail longer.

And having children/family to care for usually does affect sentencing.

So you inadvertently described the current system in the US.
