I found this video very interesting, as it defies the concept of psychological egoism. Since Ebay is a platform that is mainly based on the benevolence of the sellers, the company thought that advancing a marketing campaign that would communicate the general trustworthiness of people would be beneficial to its business. From a marketing stand point I found this to be a very successful idea, in that it centers the issue of online selling platforms and conveys the humanity of people, which, as a matter of fact, I believe to be generally true.
