 Sasha, it's always a delight to talk to somebody who reads the book closely and goes straight to the heart of what I care about because you nailed it. I mean, for me, what united all these firms, and I wasn't necessarily certain that all these companies, Coca-Cola, Delta Airlines, Walmart, FedEx, and Bank of America, which make up this book, that there was going to be a clear connection between these companies I really wanted to write about. I knew they all revolutionized various aspects of the economy, and that's why I kind of chose them.
