The mere exposure to luxury goods can have a corrosive effect on decision-making that pushes individuals to put their interests over the interests of others [individual interest at the expense of others' over mutual self-interest], according to a Harvard Business School study. ...
The students who viewed luxury goods were significantly more likely than the second group to endorse production of a new car that might pollute the environment, launch a new software with bugs, or market a video game that might induce violence, according to the study.
We can therefore plausibly expect people who enjoy actual luxury to have even less concern about the well-being of others. As octogalore puts it: "[T]he fact that things are this way is horribly, despicably unfair. And maybe so. But that’s how reality works..." God forbid we should actually take responsibility for correcting unfairness (unless that unfairness affects us personally).
I've got mine, Jack, go fuck yourself.
