I think it really does matter, in at least two ways. As a person, and as a citizen.

As a person, I find it useful to consider how I've been lucky in that a) I'm better able to take advantage of the luck I've had, and b) it makes me more careful about downside risk. It also helps keep me from a certain fat-headed overconfidence. As the line goes, "Some people are born on third base and go through life thinking they hit a triple." I think that stunts people's growth.

As a citizen it's especially important for me in figuring out how to vote and what to advocate. I'm a big believer in the veil-of-ignorance approach: [1] In helping design a society, I should do it so that I would think it fair no matter which role I played. You can look at that as a way to subtract luck from the equation.
