John Lanchester in the London Review of Books:
The moment of revelation is a little different for every person who experiences it. For Sam Walton, founder of Wal-Mart, the road to Damascus came in the form of a pair of knickers. At the time – 1945 – Walton was in his late twenties, and was running a small department store in Newport, Arkansas belonging to a franchise called Ben Franklin. Walton had grown up in Missouri and attended the state university, then gone on to a clerical job during the war. He married Helen Robson, borrowed some money from her lawyer-banker father, then opened his Ben Franklin ‘variety store’.
The life-changing pair of panties appeared in a list of goods sold by a garment-industry middleman in New York. The pants were ‘two-barred, tricot satin panties with an elastic waist’ and their price, $2 a dozen, was 50 cents cheaper than that offered by Walton’s current supplier. This differential allowed Walton to sell the knickers at four for $1 instead of three for $1. The panties began to get up off the shelves and walk out of the shop on their own.
