You also have to consider that people today have a much greater selection of things to spend their money on, and therefore want to spend proportionally less on any one thing.
For example, 50 years ago it was common for middle class people to have a really nice china set. Probably nicer than people on average have today. But that china set represented a significant investment of their total spending power. The phrase ‘prized possession’ was used a lot back then. Likewise, men often spent significant money for a good watch, but it was one of the only luxury items they’d own.
Today, you want the china set, but you also want a new TV, an iPod, a computer, two cars, all sorts of recreational equipment, VCRs, DVD players, ad infinitem. You spend money for cable TV, internet connections, cell phones, etc.
Also, back then a lot of people bought quality because the alternative to quality was absolute junk. You either got excellent hand-crafted furniture, or you had to buy cheap crap from early mass-production factories or make things yourself.
Today, you can still buy the expensive hand crafted stuff, but the mass-produced stuff is much better than it used to be, which drives down demand for the really expensive things. It’s not that the quality of good things has gotten worse, but that the quality of crappy things has gotten much better. Take that china set - if you weren’t using that, what were you likely to have? We had some godawful blue plastic dishes. Glass dishes broke easily and had simple patterns or none at all. It was clearly cheap stuff.
Today, you can buy excellent glazed dinnerware sets with nice colors and patterns for under $100. So the need for expensive china dwindles.
Add in the increased cost of labor, which pushes more and more goods into mass production. I saw an episode of “This Old House” where they were repairing some handmade balustrades on the stairwell of what would have been a lower-middle class house ca 1940. They made the point getting an estimate for a craftsman to hand-make an equivalent railing today, and the bill was $16,000. Not many middle class homes can afford a $16,000 railing for their stairs. So we get mass-produced spindles. Less choice, less customization, but FAR more efficient.
But when you compare apples to apples, say the quality of electronics today compared to 30 years ago, there’s simply no question that the new stuff is much, much better. When I was a kid we had an old RCA Victor Black and White TV, and it broke down regularly. In fact, TV’s broke down so much back in the day that ‘TV Repairman’ was a growth industry, and these guys drove around making house calls to fix TVs. It was a semi-regular thing to have the TV repairman show up. Or the appliance repairman, or the plumber, or any number of specialists who drove around keeping things working.
Poor people today have access to higher quality goods than they’ve ever had in history.
