With the increase in adoption of certain technologies (node etc) I have noticed a relationship with the people employed to work with them and their poor level of professionalism in the workplace with regard to their work and how they deal with other people (in the UK) and even how they dress. Similar age groups in other areas don't display these traits.
A number of these people work as contractors as well, so at least it was easy to get rid of them.
Go post memes on the LKML and see what happens
