MINE!!!
I believe that it is probably police officers. Very few of them make over the proverty income and they risk their life everyday. Street cops are around the most dangerous people and they are the ones that are underpaid!! No wonder they go bezerk when someone resists arrest. I would not be willing to work for their pay and risk getting killed.
The above answer is crazy, I know lots of cops that are very well off. I've never known a poor cop. The worst paying job is taco bell. Now that's poverty level.
