What I see in an ad like this other than being able to do from a smart phone:
* Now more off shore support - wealth transfer out of US
* Now more production in china - wealth transfer out of US
* Prices as percent of income were higher - likely resulting in higher profits meaning higher dividends or reinvestment, more jobs and R&D investment in US firms
* Products were built to last longer although we were moving toward the throw away society
With all that wealth transfer out of the US - did they think the good times would last forever?
*Off shore support - minimal expense keeps more profit (wealth) in US
*Production in China - see above (but wealth is concentrated on owners and financiers)
*Prices were higher because component costs were higher, not due to percentage of income or other reasons
*Products become obsolete before they become non-functional... Unprotected glass phones an exception. Average lifespan of a PC has been increasing over the last 10 years or so as hardware is out in front of software. Phones and tablet hardware, if well designed, will last through several releases of operating system hardware, even when the vendor (Apple) decides to "end support" for the older hardware.
The wealth transfer out of the US is mostly going to the middle east, in the form of oil and bombs. Moving manufacturing to the Orient hasn't produced the middle class in China the way it did in the United States during the 1st industrial revolution. That says to me the wealth has been concentrating at the top, and the evidence that the gap is widening due to the gains made by the 1%ers, and not the backpedaling of the rest of us (except from inflation) is further proof.
But this discussion is better suited to a political or economic site, so I'll go away now...
