You could reasonably argue that today, unlike in our parents' time, one median salary won't suffice, as it might have done to 'get it all' previously.
Sorry, but the world itself has changed.
We live in a far more fiercely economically competitive world economic enviroment than our parents. China can out-manufacture us at a fraction of our costs; India can out-service our IT industries at a whim; Anyone can do business with virtually anyone across the globe, without colonial or protectionist restrictions, in our new globalised world order.
To just keep up we have to work a heck of a lot harder, and to get ahead we need both partners working, saving and investing.
That's just how the world is today. The 'affordability critique' is a hoax.
I have a couple of problems with this sentiment, Belbo.
You have neglected to consider the technological advances and subsequent dramatic increases in the productive capacity of the world since our parents time.
40 years ago people were using typewriters, snail mail, bankbooks, corded power tools or hand tools to build, robotics were non existant, telephones were landlines etc - the list is endless.
Today communication/documentation is freely accessible; emails are delivered in a split second, we have online banking/cards; power tools are fantastic, cheap, and battery operated; robots build most cars/whitegoods/electronics; mobile phones are everywhere.
A logical person would think that, given the ridiculously improved productive capacity of the world, where machines do most of our work for us and many obstacles to production have been removed by technology, that not only would a single salary be sufficient, but that it would be excessive.
I agree that globalisation has severely affected Australia (to our great detriment) but consider this question seriously as an exercise - If Australia were to close its borders to absolutely everybody, importing only things taht we could not produce ourselves and exporting our excess, would we decline, survive, or thrive? Would we still need two incomes in order to sustain our standard of living?
China has such an excess of capacity that they alone could supply every single item required for consumption for the entire world. (I watched an economics lecture on youtube dealing with just this by some harvard professor, I'll link it if you're interested). The scarcity of goods and services for the world is entirely artificial, and created by those with wealth in order to preserve and grow their wealth.
We have Aussies bludging at home watching Oprah that should be working in factories. Rather than spend money building factories, we give these people a dole payment to spend on imported goods. We have an excess of all resources needed for self sufficiency, and rather than use them ourselves, for ourselves, we sell them in their raw form to foreigners who then sell them back. There is no need to compete with the Chinese in manufacture if we don't want to - that would be a race to the bottom in any event.
So I don't exactly disagree with you - the world certainly is different - but accepting it as it is as the only form in which it can exist is fatalistic and illogical. Imo what has changed is that our "leaders" are not fit to lead our country in the right direction, and our population is fast becoming a pack of spoilt, detatched brats - ignorant, entitled, apathetic, distracted, morally bankrupt, bought off with pretty iphones and little sense of community or national pride.
That's the real reason that things have become "hard". Our population are mostly a bunch of short sighted, self serving twats, and since our elected officials don't fall too far from that particular tree, they've done the same on an international level and sold this country, and future generations, out.
