Sure, doing this calculation right would require a great deal more research. Certainly, my prior would be that freeing a slave would result in a longer life expectancy, but I would not expect the gap between slave and free to instantaneously close.
I just wanted to point out that the large slave/free life expectancy gap he was presenting can work against him- and as a result he wasn't "shutting up and multiplying" correctly, which should undermine the weight of the sarcasm at the end of his post.
People want to tell everything instead of telling the best 15 words. They want to learn everything instead of the best 15 words. In this thread, instead post the best 15-words from a book you've read recently (or anything else). It has to stand on its own. It's not a summary, the whole value needs to be contained in those words.
I'll start in the comments below.
(Voted by the Schelling study group as the best exercise of the meeting.)
