There is nothing new about us humans having short-term jollies, or even medium- / long-term jollies that are non-monogamous.
Short- / medium- / long-term non-monogamous jollies goes as far back as time immemorial. As far back as the beginnings of life itself. I'm willing to bet monogamy is the new normal as far as historical longevity is concerned. I'm no anthropologist, so I'm willing to be corrected on that matter.
Also, I'd argue consumerism isn't exactly new either. People have been blowing their pay packets at their local pub since the invention of the local pub.
