Sonofgloin, failure of figures remains your fatal flaw it seems.

Nobody in any survey on food costs, includes the cost of a restaurant cooking it for you. Next, the average Australian wage is around 50 Grand a year or more. If you can't cook your own food for 5000$ a year, then you are living it up. Nothing wrong with that, but as a food comparison, the ingredients which they would compare, would not be luxury foods but everyday food.

Well actually, under the latest economic figuring of cost of living
they do just that. It has a value to you so it is taken into account.

You might have seen my comment about a paper I am studying and that
sort of thing is counted in one part. I will write it up soon.
