So are you arguing that having less luxury than others (but still luxury) causes people psychological pain, so society should give everyone everything they want? I don't think even the most hardcore communists ever asked for that.

No. You can tell that, because I didn't:
1) Assert the premise you propose, or
2) Assert the conclusion you propose.
> I don't think even the most hardcore communists ever asked for that.
Probably not. It's a ridiculous strawman you just invented.
Well, in a world where no one studied the issue, maybe.
> Being hungry, homeless or sick is an actual problem that causes people great suffering.
So is relative deprivation.
> Driving a Honda while one's neighbor drives a Ferrari shouldn't cause anyone any suffering.
"Should" and "is" aren't the same thing. One is a statement of preference, the other of reality.
