What kind of job will he be able to have a chance at?

Ok so here's the story to the best of my knowledge. A friend of mine and I were having a conversation about money and working. She's like 3 months prego and she was saying she's trying to get a job and I asked her why doesn't her kids dad try and find a job. She told me its because its really hard for him to get a job because he has a felony for a gun charge. So I'm just wondering what kind of job could this guy actually get? Is it really as hopeless as she thinks or is this guy just being a lazy ***? She just got evicted for the 3rd time and he's always going back an forth to his moms and her place when she had her apartment. She has 1 kid with one guy and two kids with this guy. She's also pregnant again. I tried convincing her he's no good but she doesn't seem to care. He also doesn't pay any kind of support. Is this weapons charge making it near impossible for him to actually work?
