Guilt for who we are

I'm not heir to a billionaire's estate (that I know of, if your a billionaire and want to adopt me, that's fine by me) but I still feel guilty for the relative affluence I was born into being brought up in the middle class of a western country. It occurs to me that whilst I feel guilty for this, I feel no guilt about being above average intelligence (per the IQ test) and not being horrendously ugly. Money, innate ability and looks all have a part to play in determining out quality of life so it is irrational of me to feel guilt for only one (I'm using this as an excuse for feeling less guilty not more).
