Human beings evolved to be surprisingly efficient. At any give moment, we are running in our heads a statistical analysis with a massive number of simultaneous inputs. We think about what we need, prioritize this list by level of necessity, analyze the perceived costs, multiply by probability of success, and divide by predicted time to reward. From this analysis, we make our choices whether or not to take action. In a system where people generally already have what they need, caring would be an inefficiency and an aberration. We have a salary, a house, food, water, companionship. We are comfortable. Why would a comfortable man care? To care for the sake of caring goes against 6 million years of evolution.
