Why did Bush sign the ADA?

I thought I would just take a look at why he put this act in force.....

The comment I appreciated most:

"Together, we must remove the physical barriers we have created and the social barriers that we have accepted. For ours will never be a truly prosperous nation until all within it prosper. For inspiration, we need look no further than our own neighbors."

"The social barriers we have accepted".....there is no need for us to continue to allow such social barriers to exist between hearing and deaf....we can be the generation to lead following generations to place more importance on deaf education and socialization and involvement of the deaf community especially in decisions that impact them the greatest!!! We can be the leaders for that change.....
