Our so-called information economy mainly serves to manage an ever faster, larger and more complex production and consumption system, of which we have only outsourced the manufacturing part.
Consequently, without the information economy — without the office — the industrial system would collape. Without the industrial system, there would be no need for the information society or the office — in fact, office work could be like it was before 1850, when the biggest bank in the US was run by just three people with a quill. 
The sustainable image of the information society — as contrasted to the dirty image of the industrial society — is built on an obsession with dividing energy use into different statistical categories, fiddling around with figures on electronic calculating tools. In other words, it’s a product of office work, hiding the true nature of office work.
