I Am Sick Of People Who Complain But Won't Fix It

I think many people love to stay negative. I read somewhere that negativity is an addiction that's hard to get rid of. I have at times complained about this and that, but I try to change that by doing something different/ just having a positive attitude. But not everyone is like this and I know a few in my family who just love to do the opposite. They will come to me with their problems, but they never take the time to fix those issues. They won't take advice, assuming that it won't help them, which leads me wonder, "then why did they come to me in the first place?"
