She does not have to carry the pregnancy. She still can have her career. The daughter and her husband can have a third person to carry the pregnancy (she and her husband's egg and sperm). As I know, 10 years ago, in US the cost was about $50,000.-- ($20k for the lady to carry the pregnancy, $30k for the doctor and hospital fees. I don't know the current cost. If her eggs are not good, they can choose from egg donor bank. They can choose to hire one to carry or she carry the pregnancy. Many wives whose husbands are soldiers in the Middle East take this as their extra income. (15% of this kind surrogate pregnancies are soldiers' wives 10 years ago.) They would have freedom to take care their kids at home while earning the extra cash.
