This is a tough position to be in. He probably sees this as you making him choose between his family and his wife.
Did your marriage vows include the usual "cleave only unto her" line? Most do, in some variation or other. The whole point of that is that the spouse comes first, before one's parents or siblings. He doesn't seem to agree.
Parents who disown an adult child for moving away are narcissistic manipulators. You and he should be free to leave the area in pursuit of jobs suitable to your educations and skills. If he refuses, he's putting them ahead of you, and that's a formula for a bad marriage.
Serious question time:
Is he counting on a sizeable inheritance he'd lose if they really did disown him?
Are there children? Divorce is very hard on them.
Could you manage financially and emotionally if he divorced you?
The answers are none of my business, but I'd be seeking marriage counseling and considering divorcing *him* if I were in your position. I might also consider taking one of those jobs and living on my own, and if he refuses to have a long-distance marriage or to join me, visiting his parents often, like grown-azz men do, then I'd sign divorce papers so long as the terms were not unfavorable.
