Fair enough but I think the good of humanity should be taken broadly. First of all any kind of primary production is basically the base of the pyramid for everything else, if you make art or entertainment thats anything less than 100% cynical in nature you're contributing a tiny amount to the general wellbeing of a huge number of people. Really anyone that makes or provides anything people enjoy in some way. I'd say it includes basically everyone except the many layers of superfluous management.
