How can I help my mother?

The mother is unhappy. The majority of her time she spends thinking how to make money. She believes that the biggest component of happiness comes from being wealthy, which she defines as making more than $200,000 a year and preferably 1,000,000. She is musician and she hates her profession because it does not bring to her the amount she wishes. Her husband earns a small paycheck too. The mother does not care what she does in life, as long as she makes $1,000,000. Thoughts about money consume her days and even years. Whenever, she sees well off families she becomes miserable and even depressed. She does not want to switch her profession because she believes she has to pay for her daughter’s college to whom she does not allow to practice any profession other than medicine. The daughter tried going to cheaper college but the mother made fun of her stating she is afraid of challenges but after agreeing to attend a more expensive school, was called selfish. Mother also demands a house and money after she retires believing it is children’s responsibility to support parents, because parents raised and educated them. Sometimes, she even demands a price. Her daughter tried explaining to her that the happiness does not come from making money. Thoughts of money should not consume all her life. This does not help. It has been lasting for five years. Nothing really changed, and even when the money mother makes increased. The daughter is tired of trying to explain her mother that while money is important it should not consume all her mother’s life. How can the daughter help? Is there anything else a daughter can do? How should the daughter act?
