Really? Which products are getting more repairable with time? Nobody is bringing back easily repairable washing machines or easily repairable automobiles.
Lots of products are more repairable now, by the owner, primarily due to the internet (YouTube specifically), along with websites dedicated to providing schematics and parts lists/ordering (Appliance Parts Pros, etc.).
I've personally repaired a broken dishwasher (temperature sensor's solder busted), the hot-surface ignitor of a gas-fired water heater, the water-filter socket of my frig, and helped a friend repair the ignitor in his gas-fired dryer.
All thanks to Youtube videos with instructions/tutorials, and the availability of parts.
Prior to these, I would have had to call a repairman, and then he'd probably say "you need a whole control board" or "the unit's dead."
Your argument is wholly incorrect, though. Manufacturers aren't making things easier to repair. Those things you repaired? They were already easily repaired. In the case of your argument, the only thing that has changed is whether or not people know how to repair things. And these days most people don't and most aren't willing to try without step by step instructions on how to.
That's partly because there's so much older stock. Also, the "easily-repairable" products of the past were not nearly as cheap! The closest comparison today would be "heavy-duty", "pro" models, often built by niche manufacturers, which do advertise ease of servicing as part of the value.
I don't know about cars, but I am typing this on a Thinkpad in which I can change the battery with no tools and can change most of the internal components without more than a screw-driver.
While true for my Thinkpad (T520), it no longer really holds for many of the latest models, with many of the T series having solderen on RAM or secondary batteries that are built-in a not easily servicable.
Being suddenly in the market for a new washing machine myself, I might argue that a large portion of the value of a washing machine is in its aesthetics. Same (probably more so) for cars. I'd probably need to put more thought into that, but I am fairly certain that aesthetics don't count for much in a tractor on a farm. It's possible that classic-styled tractors might even be mark in their favor.
If I could buy a washing machine with a 10 year warranty I would not care at all what it looked like.
My washing machine is leaking at the moment. I have to decide whether or not its worth my time pulling it outside and apart to see if it can be fixed, or if I should just go buy a new one for $750
Quality of materials [1], workmanship, capacity, ease of loading, max spin speed, gentle spin option, energy rating, water consumption, quietness, quick wash function, drums that reduce creasing and so on. Good quality washing machines are more expensive but not because of aesthetics.
