This may get downdooted to oblivion, but I think some of this is human nature. It is abhorrent, and something we need to strive to fix, but it is rather natural for people to think that their own situation is typical -- because for them, it is. Every exemplar that a privileged person will have is also a privileged exemplar -- until, of course, something like this happens.
And as a further consequence, it is extremely difficult to convince someone that their personal situation is not the norm. Everyone wants to be the main character and ultimately believes that they are.
Not sure what the solution is.
