Most handicapped people live in poverty. I'm quite convinced that a lot of privileged people are also moderately or significantly handicapped and hiding it. If you are important enough, people meet all your whackadoodle requirements without wondering why in the hell you can't do it "normally."
I've been in situations where I had privilege and I've been in situations where I couldn't get adequate accommodation for my handicap. Having privilege usually beats the tar out of having handicap accommodation.
If there are any genuinely blind people managing to supposedly "game the system" in the manner you describe, more power to them. Because trying to play it straight and do the right thing and earn my way and blah blah blah mostly seems to get me absolutely crapped all over.
