While our NZ Super isn't asset tested, our residential care subsidy (elderly care) is asset tested, and is very expensive. When you get old and don't die suddenly, then it's likely your assets you've accumulated over the years will be used to pay for your care (though there are some way around it, but not usually cost effective unless you have a large amount of assets).
But, the elder care the govt gives you (if you can't afford it aka no assets), isn't very pleasant, so you really should plan for it while you're working age, and have investments large enough to cover the costs (which most in NZ don't do).
I don't think we have insurance here that covers elder care.
I believe the guys across the ditch (Australia), have a better retirement system setup. While in NZ our Kiwisaver by default contributions are 6% (total. 3% employer, 3% employee), been this since it started just about, while in Aussie, the current min default total is 11%. Though Aussie's govt supported retirement payments are asset tested, where as they aren't in NZ.
I think having a higher min default is probably best for everyone, as most people don't change from the default.
Also, the US has 401(k) savings plans. It is pretty similar to Kiwisave.
Says who? According to whom? Who gets to make that call?
If you don't have anything then you can avoid certain costs, or sometimes you can get subsidised.
The wealthy also get some financial boosts e.g. house appreciation. And white collar crime has cheap convictions (or you can avoid consequences)
I've never had kiwisaver because I believe in the value of optionality with my own money. I severely hate locked up money. Being able to deploy money has gained me a small house worth of money. The FIF rules are a cunt to manage and Sharsies are SHIT - they've promised to deliver an FIF report but haven't done so.
Most people just don't know about it. Due to the FIF rules. Any international investments you have get taxed like this (it's not so clear cut, but more or less). The only exceptions are NZ investments and Aussie investments, maybe. There is a tool to check if an aussie share is except from the FIF rules. e.g. Aussie ETFs aren't, even if they invest in only aussie stocks...
So everyone with a Kiwisaver (retirement scheme), aka most people, have large portion invested overseas, and thus are paying the 1.4% p.a.
It also discourages high net worth people from moving to NZ, as they usually have investments outside of NZ, which will get taxed once they move here (after a few years exception).
The small "win" we do get is you can (cost bases) invest up to $50k overseas without the 1.4% FIF rules applying, (though dividends are still taxed). But like no one knows about it, and managed funds can't take advantage of this, so most people don't utilize this, especially not low income people, who generally aren't that well educated on finances.
Don't get me started on our lackluster retirement scheme, Kiwisaver, with near 0 tax incentives, and propping up the housing market prices.
