Weirdly, while I was posting my previous blog post, Eelco was watching a lecture by Elizabeth Warren. They dovetail in rather a neat way. Some of what she says is not applicable to the UK - thankfully we don't have to worry about spiralling costs for healthcare at present - but a lot of it is very surprising and very interesting.
I did that thing where you watch another and another and another... and found this video about the response to global climate change. The internet is so wonderful. I hope we save the world beore the internet melts.
