Education, education, (private) education.
I just did a bit of googling on the education of the most recent Prime Ministers, because I thought they had all be privately educated, and wanted to use that fact in a post about class and education. In fact, two of our three most recent PMs went to a state school (no prizes for guessing the odd one out.) I still don't think this necessarily proves much because none of them came from a background that could be described as anywhere near 'working class', but... I feel the need to mention this because, if my googling had confirmed my initial thoughts, I would have made a big deal of it.
