My brother refused to go out to work.

Your brother's habit of gnawing at the old is caused by your parents' improper education. They haven't found the root of the problem until now. Then I will tell you that it is their weakness and connivance that led your brother to this step by step. So if you want to change this situation, your parents must make up their minds. They can't make up their minds, and you have to do their work. They can keep him for a while, but they can't keep him for life. He is likely to despair when his parents die! It's not too late for your parents to stop providing him with the necessities of life and let him go out to make a living by himself. No matter how much he hates you, he must do so and let him eat by his own hands and labor! In our thirties and forties, we can no longer rely on our parents. He must be ruthless and thorough, otherwise he can't change. Sometimes it is cruel, but we have to face it. Finally, I wish your family an early start and hope your brother can stand on his own feet as soon as possible!
