What are the motifs in McDonald's: Behind the Arches by John F. Love?

Struggle is a recurring idea in the book. McDonald's could never have succeeded without its struggles but struggles posed its greatest threats. McDonald's earliest difficulty was surviving beyond a single store, something the McDonald brothers had to struggle with largely on their own. They had trouble selling franchises and so hired Ray Kroc to do the job. Ray had his own difficulties setting up his first store and getting people interested in buying franchise licensing.
