For Americans with disabilities, no less than for all other citizens, the opportunity to earn a living and be self-supporting is a universally held goal. Yet in perhaps no area of public policy has the expectations gap so stubbornly resisted our efforts to achieve equality. Whatever set of statistics one chooses from among the varying estimates of employment rates for Americans with disabilities, the rate and level of employment for this population remain far too low. These employment and earnings gaps are a substantial public and policy concern. A lack of employment opportunities limits the ability of many people with disabilities to fully participate in society, as employment plays a number of important roles and functions for individuals. This book comprehensively reviews the issues integral to the employment of people with disabilities.
