They have a job and they are paid for it. They also do have pensions and social security benefits: through their husbands. If the husband remains alive, they continue to be paid as they were before retirement. If he dies, they often inherent his pension and assets.

No, they are not paid. Their husbands get paid, they have all the pensions and social security benefits, not them.
Means total dependence on their husbands. If they get a divorce they have nothing.
