"Luck" is the wrong word w.r.t. your examples. It could not have been otherwise, as you are those features. You wouldn't be you if you didn't. There's no ghost in the machine that is the "real you" that is haunting a carcass where these features are like possessions that you own. You don't own them. They are (a part) of who and what you are. They are things you can, in the appropriate manner, share with others. You didn't earn them, but so what? Why is everyone obsessed with everything having to be earned? A gift also belongs to me, even if I didn't do anything to earn it, and no one is entitled to take it from me as such any more than they can take anything I have earned. Now, w.r.t. material prosperity, of course there is no reason to feel guilt. If you acquired your wealth morally, then all is well. This is distinct from the general obligation of those in our society with means that exceed their own needs to aid those in a state of poverty. Note that I said poverty, not having less. Having less is not an injustice. The framing of inequality as injustice in recently years is rather a symptom of envy or confusion rather than an impulse coming from an intelligent sensitivity to injustice.
