I met leader (Charlton) at Gallaudet and he was nice guy but he is very frustrated about deaf communities are ignored by government and deaf unemployment is very high. He has Usher Syndrome - same as mine. He left Gallaudet because of dissatisfaction with education performance in IT major.
Deaf unemployment is very complicated - they don't count anyone who born deaf or HoH that goes thorough the deaf education but I believe that late deafened with full oral language have better chance to getting hired, especially if they have very good benefit with hearing aids and don't use VR service.
The percent of unemployment (80%) seems closer to accurate for anyone who born deaf but it should be lower as 70%.
Deafblind? That's very, very, very challenging.
