As kokonut pointed out, I don't think legislation is a bad thing.
Affirmative action is different from declaring discrimination illegal. In fact, it's enforced discrimination. In in the case of discrimination being illegal, you cannot deny based on certain characteristics. In the case of Affirmative Action, you are saying you must deny based on certain characteristics.
Are you going to sue someone for not including you in a conversation?
I cannot find the documentation of when Saab was government funded(which I believe as a carry over from the war), but, as I understand it, Saab was once a government funded program which affected it's capitalistic economy. Today, the web is flooded with documents on it's latest bankruptcy so I can't find the economic case study. If I'm wrong I'll retract, but that's another whole thread in itself.
My point is, a government program is not going to solve the problem because it can't functionally do it unless it can give an incentive to do so. How do you want to reward people for including deaf in conversations? How do you create the benefit at the government level?
