John: "That's a terrible burden to impose on our children and grandchildren."
This is the guilt line used by many conservatives to make a point about "entitlement" and debt shortfalls. I don't necessarily disagree with the statement but if you're concerned about your grandchildren then don't be in denial about climate change or global warming. This to an issue that would burden the future of the planet as well as your grandchildren. If there is no planet then there no need to worry about entitlement shortfalls.
