what is the point?, page-47

There you go again, completely glazing over my points. Dual household incomes, but by your logic only applicable in Australia. If not, what am I missing?

Is Australia the only country with a significant increase in dual income households?

Nobody is disputing that if a household suddenly gets a second income, they can afford more, that's basic logic. To suggest someone doesn't understand this would be naive. My problem with your claim is you seem to imply it's a recent occurence. The year is 2010, the liberation of women allowing them to enter the workforce en-masse happened decades ago. Why would you think numbers entering the workforce, giving rise to dual income households, had spiked in the last ten years - to coincide with the boom? By what approximate margin have dual incomes increased household income in the last ten years, say to the nearest 10%?
