Scalzi has an interesting POV: http://whatever.scalzi.com/2012/05/15/straight-white-male-the-lowest-difficulty-setting-there-is/
If I wanted to win the game of life as easily as I could, I would probably create a character that is born wealthy, attractive, able-bodied, educated, great family, nice and safe location, white, and heterosexual. ...
The problem I have with this "difficulty setting" model (and to some extent the privilege concept in general) is that it portrays various personal attributes as being strict "disadvantages", while ignoring that these attributes are part of what make us who we are and shape our life experiences.
When you say that if you had omniscient powers, you would choose to be born as a person with a certain set of privileged characteristics, what you are missing is that that person wouldn't be
you at all. You ended up the way you did as a result of the sum of everything you went through in life, as influenced by certain innate characteristics. A different version of "you", born into different circumstances and facing different challenges, is not just a version of you with an easier difficulty setting -- it's a
different person entirely. When you say you would rather be that other person, what you are really saying is that you wish that
you had never existed.
Even if a person is facing a hard time in life, do you really think that they would better off
if they never existed? Most people wouldn't choose to erase themselves from existence just because they have some of the attributes in your list.
The narrative shouldn't be that it's
better to be a man than a woman, or to be neurotypical rather than autistic, or to be
thin rather than fat, or any variety of other attributes. These diverse characteristics lead to differing and intersectional life experiences that make people
different from each other (or in some cases, actually not that different), but not
worse. Any disadvantages come from societal structures, not from the characteristics.
The advocacy should be directed at making society more egalitarian for everybody, not at saying that some characteristics are worse than others.
