If money can't buy love, then why don’t Indian parents accept their son or daughter marrying a poor man or poor woman?

Actually, my brother loved a girl, but her parents didn’t accept him because he was jobless at that time. Now, she is married to another guy because her parents forced her. My brother has a job now, and if he had been employed back then, maybe he could have married her, and her parents might have accepted him. Why do Indian parents interlink everything with money and beauty instead of love and understanding?
