Remind him how amazing he is in your eyes and that other people see him in a much more positive light than he sees himself. A better job will come once he starts to work on his confidence. Tell him your parents will love him as long as he loves you and remind him that they respect what he's done for their country xx good luck xx

I feel like this is more about him and his insecurities over your parents looking down on him. He doesn't respect himself enough to meet your parents, and it's better if he gets that back.
So he needs to get a job that pays enough, and you can motivate him with that.
