OK, this article and the research it describes don't actually say anything of the kind, and it's not about us or our patients. It discusses the opposite phenomenon, that having money makes people unpleasant. I'm totally extrapolating that the converse is true, and I know you can't do that in research. Nevertheless, this is a fascinating article, and it might in fact explain some things about the acupuncture profession as a whole.
“While having money doesn’t necessarily make anybody anything,” Piff says, “the rich are way more likely to prioritize their own self-interests above the interests of other people. It makes them more likely to exhibit characteristics that we would stereotypically associate with, say, assholes.” from “The Money-Empathy Gap” by Lisa Miller in New York Magazine, 7/1/12.
And doesn't it make sense, if priming people to think about money causes their social interactions to become more selfish, that being in a context like a POCA clinic — where money is deliberately played down and set aside — might make people behave more selflessly? Read it — I bet it will make you say, “Ah- HA.”
