Not that their experiences are any more representative of "poor" than what people here write about, but there are clearly different experiences and different outcomes. Again, this is not to shame anyone--but the fact that I have to caveat an accurate description of my parents' life to assuage some unknown reader's sensibility is just crazy to me.
But for the sake of argument, I'll concede everything you've described about the "poor experience" and the emotional consequences faced by this group.
Given that, does that mean that any and every discussion among the people not in that group must be couched in ways in order to not offend the sensitive group? How / where should non-deprived people discuss the best way to play the cards they were lucky enough to be dealt?
In extremis, do we need to segregate ourselves away from the sensitive group in order to protect their delicate constitutions?
Complaining about the the "privilege" that the median HN reader/commenter is born with is like if I stumbled on to a message board for 6'8" super-athletic 18-year olds and spent all my time lecturing them about how they need to consider 5'8" kinda-athletic-once-but-now-middle-aged-me in all their discussions. Of course a programmer-centric newsboard is going to have a bunch of well-off people in it.
Now, people shouldn't be jerks--but nothing in the posted article can be construed in the least-bit mean-spirited. The goal posts seemed to have moved from "don't be a dick" to "pretend you're in a support group for X all the time". Is this where we're going?
