A social problem is one that concerns the way in which people live together in one society. A racial problem is a problem which confronts two different races who live in two separate societies even if those societies are side by side.
I was very aware of office politics because I was so baffled by them. So much so goes unsaid. No one says 'you're a cheeky so-and-so ' no one says 'you're so moody ' nobody ever confronts anyone else about anything. But I'm very crass and I'm very confrontational and I have a temper. I had to be hyper-vigilant in every office I worked in.
