There are good clicker trainers and there are bad clicker trainers. Good clicker trainers use treats randomly. If you treat each and every time you make a command, then yes, your dog will eventually assume that he gets a treat everytime you click--I mean wouldn't you? However, randomly using treats and making it feel like a game means that the training remains fun.
As for the sharing of resources, wolves definetly share their food with members of the pack otherwise how would the pack survive. The top wolf just lets the other members eat--which is exactly what you are doing with treats. If a member of the pack disregards the rules of the top wolf, then top wolf will not let him eat, or growl, ignore, fight or send him away. Simple as that.
The thing is, dogs do see humans as different from themselves, otherwise why would they adapt to our demands like peeing in one spot, rolling over, giving paw and doing tricks for our approval. Every behaviour within a household is very different from living in the wild. Dogs are not wolves and wolves are certainly not dogs--although they do share some of the same instincts. And yes, a wolf will not ask a member of its pack to do tricks for a piece of meat but it will share meat for being cooperative.
Did you know that wolves do not bark? Barking is completely dog. As well, with between 20,000 - 50,000 years of ancestry between wolf and dog the ancestry is so removed that dogs and wolves are very different--just looking at the appearence of dogs vs. wolves is evidence enough. Dogs are more scavengers than hunters--that is how they became domesticated. If a dog is a scavenger then it makes complete sense how dogs respond so well to treats. I don't think it would be possible to clicker train a feral wolf unless the training were started very early on.
