Don, I'd like to say that I feel your pain but you know better than I that I truly can't. I'm pretty much an average white guy pushing 60 and cannot even begin to relate to the kind of trouble that your condition brings to you. I don't think there is any gray area with Cerebral Palsy. In my mind it easily clears the "true needs" bar.
A hard libertarian would say that the government has no business being in the safety net business, ever, but in all honesty, I'm not that hard of a libertarian. I'd like to think that everybody who truly needed help, could and would be helped by private charities and organizations, but that I'm afraid is a dream. So I am in favor of a government safety net for the truly deserving.
Don, I understand your frustration with employers. Do you think things are getting better though? A hundred years ago the employment options for somebody with a serious physical disability must have been almost non-existent but in the information age aren't the opportunities a bit more available?
