Mine has. Goods are much cheaper, and we can afford more of them. I guess we'd be better off if we could only buy higher priced, lower quality goods, and couldn't choose from the productive output of the world. Now, if a family feels the need to 'keep up with the Joneses' they can got the two income route. It's their choice what is more important to them. Imagine for a moment if your home only had in it what a home in the 1950's had (when a TV cost half the average annual wage). Are you saying you couldn't pull that on one income? People always want more, what they do to achieve it, and what they balance against it, is up to them, as it should be.
So have those of the overwhelming majority of this country.
