My Elder Brother Greed

Hi.. we have a joint family living together in a 4 floor 2000 sq ft building, Me, my wife and only daughter, My elder brother his wife and his only child than at last our parents. We are all living under one roof and on a same floor. I am into private job from past 10-12 Yrs and earning bread and butter from it. whereas on the other hand my brother had started small business with my mother on our building's top floor . Our most of House hold income come through other floor as Rent and PG. So he (my Brother ) get his expenses done through our rent and businesses. whereas i don't believe in taking money from house instead i am doing my best to earn by my own through my private job. So Now my Elder Brother's greed is extended to that level that now he wants a control on every thing, He named business on his name although property is still entitled to my parents name. But he abuses and wishes for their death, He harass and disgust the whole family environment. Please suggest how to pacify whole situation, and to control this greedy beast.
