The Ethics of Special Needs: It's a Matter of Fairness 

The American Disabilities Act (ADA) of 1990 cites 43 million Americans as having disabilities. Despite the progress the ADA represents in improving equality of opportunity for those with disabilities, much remains to be done--as evidenced by the fact that only 27.8% of working-age people with work disabilities have jobs, compared to 76.8% of those without disabilities. The statistics are even bleaker for minorities.
