In USA, deaf people have survived all these years
without ADA, without interpreters, without captions.
They were called deaf-mutes, and public attitude
towards deafness was somewhat negative.

Many deaf people were gainfully employed.

And we had Deaf Success stories such as
professional athletes (Dummy Hoy, Dummy
Taylor), and in some difficult fields
such as as embassy diplomats, intelligence
spies, elected public officials. Even
one deaf man owned a big printing shop in
New York City that employed many people.

This is not to say deaf people didn’t need
ADA in the past; they needed it but was able
to survive without it!
