One of my friends is a blind coder (and he sometimes comments here on HN), and he's had a very hard time getting regular work as a coder, even for things that seem obvious (like testing and fixing apps and sites for accessibility).

The city I live in had a systematic problem with loud speakers announcements on trains. Blind people rely on these announcements to know which station they are at. And trains speaker systems were mostly broken or heavily distorted on nearly every carriage.

I share a house with my physically disabled sister who deals with similar problems nearly everyday. My sister was lucky enough to find employment with a government agency that takes it's responsibilities towards disabled people seriously, but many disabled people still disengage from society because of the extreme hassle involved in something so simple for the rest of us, like getting to work.
