Your sister is very independent and envious. To tell the truth, the present marriage is really different from the previous one. A woman is not attached to a man, but just looking for a partner to get along with, so there is nothing wrong with your sister's approach, which has little contradiction with her future husband's material interests. If she is unhappy in the future, she may live better than men. Young people don't work hard, and the boss is sad, regardless of gender.
