They talk and never listen, listening would mean they have to take into account their surroundings and well that would spell disaster for many people. They would have take in to account how all their dreams and hopes were lying shattered around their ankles. They can never afford that house they really want, they will never be paid enough to do that but rather than give up they carry on doing the same mundane tasks that are rotting their life away from the inside of their soul to the outside selling of their labour.
They will sit and tell you how they are not a slave to money but they will always describe themselves by the job that they do. They will never describe themselves in any other way unless they are unemployed and then a form of shame will come over them and they will be a freelance shelf stacker or something similar. Just waiting for that right vacancy to come along, it never does and this is why people can not communicate.
