Someone still trying to increase his 'fan' base here.
Please tell us how you arrived at and what conclusions you are pointing out in your tide statement?
Does the report show how much debt or liabilities the household have?
Does it show the cash reserves that the household have?
What about rich semi-retirees whose income may be low (say earning only token director's fees for e.g) but sitting on a huge mountain of cash? Does the report show you the actual financial position of such households?
Walk around the nearest mature landed neighbourhood. How many houses do you see with older couples who have lived there for years and probably have zero loans on their property. Their sons or daughter who are still living with them may have just started work.
Household income doesn't prove a thing until you know the full financial position.
