generation. To top that off we presently have the most generous (60% of average wage) and universal state provided pension on the planet.  I'm all for treating our elderly citizens with respect and believe they (and everyone) is entitled to live and die in dignity - but not at the expense of future generations.   Something has to change - and what I like most about the Big Kahuna is that it encourages self-help options.  An elderly person living alone presently gets a larger pension than one living with a partner.  With the Kahuna, one doesn't get "punished" for sharing accomodation with others - be you a pensioner or a solo parent.  Much wiser use of our housing stock would result over time, I assume. Who are these young families who can not afford a deposit on a home?  Because I see lots of young families happy to spend up on trips to the Gold Coast, big 4wd vehicles and flat screen tvs. It is a myth that property is unaffordable.  It may be expensive in Central Auckland, but elsewhere property is relatively cheap. A comfortable home can be purchased in the Wellington suburbs for $400k, in ChCh suburbs for under $300k, in Dunedin for $200k, or in South Auckland for $300k. That is hardly reason for a change in taxation which would see people penalised for paying off their mortgage.  All that would be acheived by Morgan's tax would be making it harder for someone to own their own home
