Aside from furloughs, the impact of sequestration on civilian defense workers in Colorado Springs, Colo., has been minimal, observers say. The region has been largely spared because of the types of defense contractors operating there, according to some experts. "It's really hard to know what the overall effects of sequestration might be on the economy," one economics professor said. "But there's a theory in economics -- people only change their spending habits when they know a change of income is permanent. Since this isn't permanent, it isn't likely to change many habits."
