Because the public has 1 of 2 views of the deaf.
1) Deaf people are lazy, mooching off of the government and taxpayers out of self pity while scamming the system by selling drugs or working for pay under the table.
2) Being deaf is so sad. We have to take care of those people because they can't take care of themselves
Both of those views are a bunch of crap. We have many hard working, industrious, self supporting (even thriving) people here on AD alone. But, when able bodied people take advantage of the system and taxpayers, they feed these negative stereotypes. PLUS they take funds from people who truly need them.
Wanting weekends off, wanting more money or having to work long hours are not a disabilities. These are facts of life that everyone faces. Hostile work environments are not reserved for the deaf either. Tons of hearing people have unpleasant work environments as well.
