I think objectivists usually do a pretty poor job of articulating the philosophy... that thread seems to be no exception.

This is a pretty good list of the value judgments typically made by objectivists, and more generally libertarian-capitalists:

'First, in our system "underprivileged" people essentially do not exist. The percentage of people genuinely unable to support themselves is infintesimal. We do have quite a collection of moochers and bums, but that is no one's responsibility but their own.' 'What would stop welfare recipients from becoming working, productive members of society when their taxpayer-looted dole is cut off? Nothing but sheer laziness and a continued desire to remain parasites, in defiance of reality' etc.

And that was a great list of broad generalizations by you! Thanks for illustrating.
