Why we need the pension plan

In La Paz, we see few street people. I have come across two or three so far who seemed to have alcoholism problems. All the rest are just the elderly. It is a different make up than the extremely poor population we see at home. The beggars are very old, poorly dressed, unfailingly polite, and alone. I have to assume that they have no children to care for them in their old age, and no place to go. It is incredibly sad.
