My Sock Market Crashed tells of a boy, Dylan, helping his grandmother sell the beautiful socks she knits. A venture into mass production is abandoned because Grammy could not knit fast enough to supply her popular socks for the demand, and the socks provided by the mass-production company were not nearly as desirable as Grammy's. Dylan rescues the situation by redirecting Grammy's socks to help children in the hospital. The book endorses public efforts to provide socks to the needy.
