I've always detested the "newer is always better" mentality that the population seems to have been conditioned into, and that the culture perpetuates; I think when the only reason you want to buy a new X is because your existing one is "old" (not unfixably broken, not slow, not missing a feature that would really improve your life), there is something seriously wrong.
People see energy star ratings and Amazon ads, neither of which emphasize lifespan, durability, or repairability. It's like the MHz wars for white goods.
The next level of information is Amazon reviews — generally dominated by people who just bought or don't even own the product... e.g. Nikon and Canon fanboys will go and sabotage the ratings of their arch enemy's products. If you're lucky you sometimes find a review by someone who has owned the product for a whole year.
The ease of price comparison has led to SKU-mutation where the same product is sold in micro variants. This also makes more thoughtful reviews, such as those by Consumer Reports, useless because they can't survey a product field or provide reviews that remain useful for more than a few months (when I subscribed to Consumer Reports I could never find their recommended products on sale -- never).
It's a situation in which rewards two kinds of players — long term brand/relationship builders who try to sell on repeat business based on trust, and short-term commodity-makers who operate on wafer thin margins and think of their product and customer relationship as disposable. Let's say Braun (or one of the other often unaffordably expensive German appliance brands) at one extreme and LG towards the other (there are far worse, LG at least is trying to be a brand).
So it's just like the smartphone wars.
Its motivation was a different problem, recycling rates: most people balk at paying a fee at the time of disposal to recycle something. If recycling costs money (as it generally does for electronic waste, which doesn't recover enough valuable metals to pay for the process), then people just dump things in the trash instead, even if that's illegal. Collecting the cost of recycling up front, and then making it free to recycle at the point of disposal, greatly increases how willing people are to put their electronic waste into the right bin.
As far as I know that's so far mostly for computers, not appliances, and only in some jurisdictions. How effective it is also depends on how strong the other laws around recycling are: if "recycling" ends up consisting of just shipping the waste to China to be processed in a questionable manner, the up-front price might not be fully pricing in the environmental damage. Overall I think it's a good model, though, to combine responsible-disposal requirements with up-front collection of the funds to do the disposal.
Anecdote: Just over a decade ago I moved into a house that was empty of appliances thanks to an all too successful estate sale. Literally every single appliance has broken since then, some more than once. I'm lucky that my parents taught me to fix things.
But I remember watching my dad fix appliances, meaning that they weren't 100% reliable back then either. And one thing that might bias my "statistics" is that there are a lot more appliances nowadays. Things that were only barely coming into prevalence while I was growing up: Microwave, home computer, electric toothbrush (yes, I've repaired one), air conditioner (rare in my hometown), various garden implements, etc. Things that don't even need to be an appliance, but are now electric, break.
At least for "major" appliances, I tend to choose based on my best guess of serviceability. I avoid models that have too much electronics, not because I expect those parts to break, but because the complexity might frustrate diagnosis in the future.
There's a lot of repair information online. People enjoy blogging about their successful repairs. But judging from comments on web forums, I'm guessing that a lot of people doing these repairs are landlords. If you buy 15 dryers, and they all break on the same day for the same reason, you'll have a pretty strong incentive to figure out how to fix them.
There's some debate of this exact issue among musicians who play amplified instruments, as I do. There are now tiny little amplifiers, but if you open them up, it's apparent that diagnosis of the circuits (switch mode power supplies and amplifiers) would be daunting, even for a pretty serious electronics enthusiast. There are players who will avoid these products for this reason. I've decided in that case that I will take the risk of having to replace a module or an entire unit in the future, because the portability is actually a benefit.
Indeed there is, and one of the sad things is that this proliferation of easy access to information has seemingly not had much effect on the throwaway consumerism of today's culture, nor in getting people to understand more about the machines they use. A service manual is often literally a Google away (even for older models, there are a lot of neighbourly people who digitise them), and although I've not needed to do any major repairs on my white goods, I've collected from the Internet all the information I need to for most if not all of them.
I called tons of GE parts suppliers and they could not procure a sequencer. Now I would just 3d print the one gear that had worn out. :(
Where it is scraped and mostly recycled.
Is re-use figured into your environmental calculations?
When it was time to scrap the computer equipment I would have profited from that, too, if not for the CRTs. Those I would have been better off throwing them into the landfill.
My aunt's first microwave cost a fortune in the early 70s - a month's salary, easy.
I can buy one at Wal-Mart today for $60.
If we all switched, tomorrow, to using long-lived appliances and goods, we'd pay higher costs for _new_ manufactured goods because their a whole lot of their inputs comes from recycled material.
Example: a metal foundry in my home town makes a whole lot of man-hole covers (and like goods). They exclusively use recycled metal. The car that I scrapped last week could be part of a manhole cover next month!
Truthfully, I'm not sure if I'm happy or sad being the catalyst of that wheel.
There is this: the toys we're making now are more efficient, easier on the environment, produce less waste in manufacturing and operation, and are even easier to part out for recycling.
By all means, keep driving that '57 Chevy around. But you're better off, and _we_ are better off, if you drive a late-model car.
