Could we not at least make various unchanging standards?

Like, housing & food inflation index?

Is that not vague and unchanging enough?

I know sourcing the data isn't a walk in the park, but I know for a fact Victoria collects information on the first one pretty accurately.

I think we should have a "base needs" basket, because that's never going to change. People need to eat, people need to sleep.

Thanks for indulging me in my vague, unlearned on the topic, questioning!
