It is this only because they won't eliminate the contribution cap. That would keep it funded for decades and give us plenty of time to come up with something better.

You're supposed to raise your kids to want to take care of you. Sounds like you either got different treatment, or tolerate more abuse.
I tell parents of those kinds of kids, don't leave them ANYTHING, let them figure it out on their own when you die.
I've had to figure it out on my own for the most part anyway because my parents were so terrible at parenting. My father did teach me one valuable lesson, pay attention, but as he frequently did it with his hand I didn't grow up with a lot of affection for him.
