Actually, I think you'll find a lot of people will opt for part time lower income jobs than before as they are just supplementing the guaranteed income which means that there is net total more than before.
The information that is added is that the knowledge is made common or infinite degree (ie. everyone knows that everyone knows that everyone knows......that there is someone with blue eyes)
The measure used here is a little suspect. Looking at words used in webpages is a pretty poor measure when many languages have little handwritten language to start with. I just returned from a remote tribal group (The Khasi) in India last month and although their web page penetration may be low, they all facebook or text in their local language. I doubt these social aspects are measured and thus miss widespread use of many languages. Public webpages are often wanted to grow beyond your small group and if a writer knows a more common language, then he would rightly use that to grow the sphere of understanding.
