I Have a Question

can someone please tell me why its so easy for people people that are disabled or out of jail to get jobs while i cant get one? I know guys that are special needs that get hired just like that doing stuff like factory work while if i try and go to the same place for a job they wont hire me, also, i know this girl from church that was going to this bible study and used to be on meth and was working at the golden corral, if i was to go there i doubt they would hire me, shes back in jail now and i heard she was out on bail and had done stuff like assault and attempted murder, and once she went to trial she got locked up again. she was out for a while. ive never been in jail or done drugs so why do people that do that get jobs like that while the rest of us that never got in trouble are forced to live without a job. so why?
