For more and more people, work appears to serve no purpose
This is one lesson you learn if you work in consulting. The biggest, most important companies in the world are chock-full full of glorified paper pushers. I spent six months working at a Fortune 500 company building a system to give mid-level knowledge workers better access to their data. I've never felt as demotivated as I did when I realized that at the end of they day they were just producing PDFs that were immediately archived away without ever being read by another human.
