This is pretty good. BTW, the guy that tweeted this has a book coming out soon named Troubled about growing up on foster homes and in poverty, and how he then went to college at Yale and then got a PhD at Caimbridge and the book is about social classes in the US and it looks pretty good. I've pre-ordered it and if you're a book person maybe you should too, or maybe wait until you're local library gets it and checks it out.
