I don't see how this is any different than people who don't want public health care options, family assistance for low-income households, and public school funding when they send their kids to private schools. If anything, these kids learned that value and ideology perfect if they are the children of such parents. Turn your back on the misfortune and suffering of others if it doesn't invade or effect your life.
Teach your children that the world doesn't care about them, and you can rest assured they won't care about the world.
