Well-paid is the keyword. I think it's safe to say programmers earn more than average people. From my observations people usually spend proportionally to what they earn.

EDIT: To make it more clear, I think resource use almost perfectly correlates with spending. One might argue, "But spending on services like plumbers, waiters or therapists doesn't directly consume resources." Yet, when you pay someone for their time, they use that money to buy food, housing, or services from others. This chain continues recursively, ultimately leading to resource consumption.

I don't know about that. I would bet my computer uses far less energy than the average vehicle in someone's commute.
