Theorists argue that structural violence is embedded in the current world system; this form of violence, which is centered on apparently inequitable social arrangements, is not inevitable. Ending the global problem of structural violence will require actions that may seem unfeasible in the short term. To some, this indicates that it may be easier to devote resources to minimizing the harmful impacts of structural violence. Others, such as futurist Wendell Bell, see a need for long-term vision to guide projects for social justice. Many structural violences, such as racism and sexism, have become such a common occurrence in society that they appear almost invisible. Despite this fact, sexism and racism have been the focus of intense cultural and political resistance for many decades. Significant reform has been accomplished, though the project remains incomplete.
