What is the main conflict in Sam Walton, Made in America: My Story by Sam Walton?

The autobiography of Sam Walton is an overview of the creation of Wal-Mart as much as it is an analysis of the man who started the discount store, Sam Walton. The novel is less of an autobiography than a bible for the small business owner. Sam offers plenty of advice and detail about how he managed to work against the odds and challenges of growing up in the Great Depression to becoming the richest man in America.
