Everyone might not have it as easy as you do, or might not be as good as you at something, or might not run a business as well as you do. I can't count the number of people I know who live paycheck to paycheck. They are "in deep, deep trouble already." I know many small business owners who are "in deep, deep trouble already." You act as if the only choice is throwing those people away or throwing the visually impaired away.
Most of this thread seems to say one has to be absolutely for this, or one has to hate the blind and have no compassion for the disabled. It would be nice if everything were so easy.
