And it's interesting cuz a lot of other phenomenon seem to arise from these ideas.

For instance, there's a more readily accepted premise that men are only accepted if they're "useful". TONS of men feel this way. This is the next phase of what I mentioned above. Men (as a sub-group) begin to filter potential comrades/community members based on whether they could be adventure/hunt/fighting partners. Of course the "hunt" is not an actual hunt but a business, sports team, etc.
