What does Facebook produce?
I mean, they run a web-page that people use to post about what they eat and pictures of their cats n dogs.
Most anything people do on that page is waste their own time and that of their employers.
And I work at an ISP that doesn't really produce anything either, apart from heat (and a bit of CO2, in case the Diesels run). We run mail servers so that people can send out virtual stuff about their often virtual goods in their virtual business, we run web-servers where shops run that sometimes even sell physical goods that the company manufactured themselves. And then there's the countless other servers that run countless other stuff from various companies, few of what they do directly relates to the physical world and as such, is pretty much useless, in the grand scheme of things.
I sometimes envy bakers, butchers or carpenters.
