Should I Leave My Husband and Find a More Financially Stable Man?

I don't know if I should spend the rest of my life with him. He does not have a high earning job, which I see as an indication of an unstable future. The average guy who's going to have a master's degree is going to be the earner. It's okay for a woman to say this and want this in a way that it's not for a man. But that has to be ironed out and understood clearly prior to getting married.
