Hi there guys, I am thinking that in prehistoric times before money the way someone became wealthy was by having skills and knowing how to do things that were valuable to other men. Like for example if a caveman was able to make spears well and all kinds of weapons then he would be valuable to other men and therefore would be "wealthy". I am guessing that maybe this has something to do with status amongst men. Like if a guy is able to help out his community of men somehow then maybe this creates status. Its just my guess.
