The significance of the Mussel Slough myth in the history of California and the Southern Pacific Railroad is evident from a quote by Theodore Roosevelt, who as president focused considerable time and energy in redressing the wrongs and abuses of corporate monopolies throughout the U.S. After reading Norris' "The Octopus", Roosevelt stated he was "inclined to think [...] that conditions were worse in California than elsewhere." These mythic narratives about Mussel Slough helped bolster public anti-railroad sentiments, and encouraged continued rebellion among homesteaders, squatters and poachers against railroad land agents, who "came to accept squatters as an ordinary, if disagreeable, part of the land business".
