Quote from Random.Capital:
Because back then the average family had one breadwinner. Now the average family has two. Therefore, to keep up with the average, two incomes are required.
In between "then" and "now" were a whole bunch of years where a family could get ahead of its peers by having an extra wage earner - this being capitalism, that advantage has been more or less erased by people rushing in to take advantage of it. So now two wage earners just keeps you even.
In addition, because of the increase in real household income, the very definition of "keeping even" has changed. Now it's a McMansion, whereas before it was a bungalow in a LevittTown.
Not very complicated at all, basic market principles.
Re: inflation, your comments are irrelevant until you put together a comprehensive replacement. Until you do, you're just making up numbers to suit your argument.
Cheers.
Per capita income (by household) was the same today (with two workers), than it was back in the 50's and 60's (with one worker). The inflation stats are obviously rigged. I'm surprised you even consider them valid. A better formula? Easy. No hedonics, food + fuel, no price substitution.
A growing labor force cannot 'outspend' the deflationary effect it lends to CPI. Labor income and production offset each other. Income can't outspend production. Only private and Government debt can do that. Incidentally, a huge explosion in both punctuated the late 60's onward (Cold War spending, Viet Nam, Korea etc). Deflating prices from cheaper, more available labor, and technology/innovation, get destroyed by expansionary money supply and Government deficits. A close second, is the consumer debt market banks opened up in the 50's. Your argument that's its only consumer spending is false. Its consumer *Debt* spending AND, equally important, Government deficit spending.
The standard of living being higher now is an illusion. Yes, we have better (and more plentiful) goods. But hasn't that always been the case? A horse and buggie to a model T. To oldsmobile. From a telegraph to the phone etc.
Second, all this "wealth" is DEBT. Period. Nowadays, everyone is levered to the Tits, and all this perceived equity in shiny new cars, McMansions and electronics is almost entirely "consumer financed".
Take a per capita equity graph comparing the 60's and present using REALISTIC inflation, and the 60's would blow us away. Guaranteed.
