Out of a sample size of 2, then, 100% of us care about the welfare of others and would not selfishly improve our condition if it meant harming others. This is not much data, so I did an experiment. I looked through my phone's contact list and counted all the people I think I know well enough to decide if they are also like us. By the time I got to about 50, there were none of whom I was certain they would be willing to hurt others to get ahead, and only a few of whom I was not sure. The majority of the people I know seem decent and I believe they are also very uncomfortable seeing other humans suffer. Is your experience different? Do you know a lot of people who, in this scenario, would be comfortable paying a "pittance" to have people mow their lawn and wash their car, not caring that they are trying to "keep their family alive"?You or I, as human beings, are uncomfortable, and wish to improve the wealth of our society. Good on us, but we're a tiny minority.
