Yeah, screw those old people with their houses! We should deliberately kill them off so that we can have cheaper houses! But please, don't let the next generation do that to us when housing turns out to be expensive for them too!
I have yet to see my government subsidise dangerous recreations based on a cost benefit analysis.
I think government costs for a retiree are about NZD27000 a year.
A government should be subsidising a good deadly recreation for say NZD10000 a year. Assume expected life remaining is 10 years, assume recreation has a 10% chance of clean death, assume low chance of expensive ongoing chronic outcomes.
Maybe a better way would be to allow people to gamble with their lives to win a few tens of thousands (need to balance costs against expected savings). Pay out to winners, but saves the government their expected lifetime of expenses for the losers. Let the old and unhappy roll-the-dice and the winners get to live it up a little . . .
