"Money can buy happiness, at least when you spend it on others."
The reason, writes Gardener, is that "pro-social" giving enhances the community:
""Reaching out and doing things for other people allows you to kind of create a community," said Dr. Alan Manevitz, a clinical psychiatrist at New York-Presbyterian Hospital/Weill Cornell Medical Center in New York City. "Social networks, we know, make people happier. It's all about creating social networks and community ties and having a sense of self that you feel is worthwhile so money therefore can be used in service of that."
And money is just one resource that can be used to that end, Dunn said. "All kinds of resources may be beneficial for our well-being," she added."
