How about I tell my brother he needs to help the family more than anyone else?
Why would you tell your brother that?
I do not think my brother knows the right thing to do here. He needs to listen to me.
You shouldn't tell your brother what he should do. If your family needs help, you can ask him to help but don't force him to.
I can't believe you care more about my brother than me.
I don't at all, and I don't even know your brother. All that I am saying is that telling others what they should do is demeaning and rude towards them. Would you want people to tell you what to do with your money?
