I think it's unrealistic to expect everyone in an organization to "buy in" to the mission to the point where everyone is contributing to the common good, due to high turnover, policies, individual personalities, or simply the challenges the industry presents. A realistic goal is to have a climate where a majority of the organization is working for the common good, but actively trying to bring the others along. Not to be pessimitic, but the culture described is obviously an ideal to be strived for, but rarely reached.
