Life is not fair.
I presume "unearned privilege" equates to the children of the wealthy who get a head start in life as opposed to the child of the poor single parent that is at a disadvantage.
We can give the poor children the best chance to succeed by giving them a sound education so they have the tools to obtain their goals. I am sorry to say, that our education system is failing to do that. Parents are failing to do their parenting, politicians fail at offering good policies and the poor are suffering. But, so are the middle class who are not getting what they need either.
Now that I have thoroughly depressed myself, I better go finish my christmas decorations.
