mine is:
1-being punished for another person's sins ( original sin)
2-that God didn't treat all people equaly
3-that a king or noble person, can both enjoy life , command people, be respected by a pope and be a saint.
4-that nobility are higher than commonfolk, just because they are born of noble parents.
5-that oversleeping is sin!
6-that marriage is a sacrament while virginity is not.
and so on...

2. God gives us all a chance to save our soul, though some people get less graces than others. It might be because God foresees they will reject a greater number of graces, and thus have a more painful eternity in Hell.
In some ways, though, He does treat us the same. He loves us all, enough to die for each one of us. He will forgive ANYONE their sins, if they follow the means He designed (confession to a priest) and are truly sorry for them. He will grant eternal life in Heaven to anyone that loves Him and follows His law.

3. God rewards you for the level of charity (love of God) you have in your soul.  A king might have an easier time giving alms, for example, so he gains less merit in doing so. Also, don't forget that the king doesn't have it as easy as you think. They have many more "cares and worries" with the welfare of their entire nation on their minds at all times. We have a saying here, "The grass is always greener on the other side of the fence."

4. Nobility is a social/secular question, and not one that the Church gets involved with. Before God, we are all equal. On earth, we all have different talents and abilities. But I'm sure that there were often smarter, stronger, etc. people among the "commonfolk" and weaker, less virtuous, less intelligent people among the "nobility". At any rate, most nations don't have nobility anymore, so the issue isn't very relevant to the modern age.

5. Getting sufficient sleep is not a sin. Some people need more sleep than others. Just like with food -- a gluttonous quantity of food for one person is fasting for another.
If you neglect your duty of state by sitting on the couch or laying in bed all day, that would be a (probably venial) sin of laziness -- wasting time that God gave you. A close cousin to spending too much time (unprofitably -- or purely for recreation) on the Internet or watching TV.

6. As I said before, God does value consecrated virginity. There have always been communities of men and communities of women who consecrate their lives to God. Theirs is a higher calling than the married life. Singles are encouraged to at least try out (for a time) such a life, and determine if God is calling them to such a state.
