The Americans with Disabilities Act claims that "The continuing existence of unfair and unnecessary discrimination and prejudice denies people with disabilities the opportunity to compete on an equal basis."

The Americans with Disabilities Act (ADA) became a law in 1990, and it's a civil rights law that disallows discrimination or prejudice against individuals with disabilities in all areas of public life including jobs, housing, and schools.

Explanation:

The ADA is saying (claiming) that unfair and unnecessary discrimination and prejudice against people with disabilities is continuing (on going, even with the ADA in place).  

And, because it is continuing, it is preventing people with disabilities to compete on an equal basis. (i.e., if a disabled person is applying for a job, an apartment, or a school, a person Not disabled would be more likely to fill those positions because of unfair discrimination and prejudice against the disabled person.)
