I am in NYC staying with my parents. Their apartment has plenty of photos of all us covering several decades. There are pictures of my grandparents when they were younger than I am now. I’ m learning that I am a sentimental fellow. I see my high school yearbook but I won’t thumb through it because I have to get some work done. I did want to plug this new book by Acemoglu and Robinson. Cambridge economists have earned the right to do “big think”.
