If you are 30 that is essential meaningless, like saying you do not care about pensions. If you are 60 both statements carry a lot more weight.

Very weird idea. Like, if you're 30, you should be socking money away for your retirement, not relying on your kids to support you when you're old. And also, by the time you are 60 you should have built up a large and supportive group of friends to make sure you aren't lonely, not rely on your kids to keep you company. Pretty much no one I know between the ages of 20 and 40 lives in the same city as their parents, and they visit them once per year for Thanksgiving or Christmas. If you are having kids so you won't be lonely... it's a bad bet.
