Localism often exists due to socioeconomic factors as well. Until relatively recently, surfers were looked down upon as lazy people on the fringe of society (hence the term "beach bum.") Many who surfed were locals who lived in a beach town year-round, and were from a lower economic class. For that reason, these groups were resentful of outsiders, particularly those who were well-to-do and came to their beaches to surf recreationally rather than as a way of life. Australia has its own history where surfers were openly treated with hostility from local governments in the sport's early days, and the tension never really went away, despite the sport's enormous increase in popularity. Maroubra Beach in Australia became infamous for localism and other violence chronicled in the documentary film "Bra Boys" about the eponymous group, although the surfers in the film maintain they are not a "gang."
