The solution to this is more creampies 20 years ago, no government action can change that. Every generation pays for the retirement of the previous one and if a generation makes less kids then they put higher burden on those kids. Before the taxes and pensions people used to look after their aging parents, today people who live in cities and pay taxes so that they can have independent lives from their parents. That's how biology works, people born procreate age and die and if you live in a society the young ones take care of the old onces until they die.
