I know from personal experience what a challenge it is for someone with AS to get and keep a job, much less build a career, but I also know it can be done for long periods of time when you know you don't have any other choice. I think if someone cannot ever live on their own, pay bills, prepare their own meals, and do their own laundry they are not high functioning and should have their diagnosis reclassified to LFA.
My biggest problem with Rainman is that they refer to Raymond Babbit as 'High Functioning' when he clearly is not. Being able to toilet yourself and tie your own shoes isn't very functional if that's all you can do without supervision.

Yes, but '
partially' means you've made a real
effort to manage independently. Needing help is one thing, letting others do
everything for you is just succumbing to weakness. If not for my family, I'd have crashed and burned several times over, but I kept getting back up and going back out there because there wasn't any alternative - I didn't know I had a handicap, I just thought I was a screwup.
There did come a point eventually at which I ran out of options and couldn't keep going on my own, but I would if I could. I hate being dependent on others, it makes me feel like a prisoner. And when you're perfectly capable of working and want to, but are being barred from it by discrimination against your disability, its even worse.
