Providing access to educational and employment opportunities for disabled persons is one the least controversial of the topics addressed in Chapter 8, as it seems to be a clear way of demonstrating respect for such persons’ dignity, and as the costs of such access seem very likely to be offset (or more than offset) by the advantages to society (not to mention the individuals themselves).
The Americans with Disabilities Act [ADA] was passed into law in 1990; prior to 1990, anyone with a disability could be denied employment, education, even service in a store or restaurant.
