I dont think it should be means tested.
But I do think the age should be near 80, not 65.
The people that have wealth will have paid one metric f*ckton of tax over the decades, so why shouldn't they get their bit when they get old?
The problem is fairness, Perhaps 80 is a bit tongue in cheek but in any case raising the age of eligibility is unfair to certain groups of people, usually the poorest. People who have engaged in manual labour for their entire work lives are more likely to have worn out and broken bodies and simply unable to work into the dotage. Certain groups of die earlier for example Maori and Pacifica people’s so is it fair that a person with a better genetic background should get a greater advantage through legislation?
As for tax, one of the wealthiest businessmen I know told me he does not resent paying tax because that means that he is making money. I would love to pay the most tax in New Zealand!
