chuckle it is oddly reassuring to hear somebody's worries and complaints, Especially when from a country like New Zealand--apparently, New Zealand is so great that even our billionaires want to move to move there.
There are plenty of resources to support retirees, even in the face of declining population. After all, people have been paying into the system their whole lives---what did the government do with all that money? Making New Zealand richer. Over the last 30 years, your GDP has quadrupled, and yet your population grew by less than 2 million people.
If our parents could support our grandparents with 1/4th of the GDP, our kids can certainly afford us in the future, when the GDP will be even higher.
Workers these days are incredibly productive. Trying to get everybody scared is just creating a false problem. True, instead of sending the dollars to defense contractors and billionaires (Its amazing how the U.S. was suddenly able to spend another trillion on the Iran war, eh? Always plenty of money for that.)
