This has been something I've really thought about in depth already - like so many of us 'old timers' have.
Seems to me: Everything after the year
1989 has a 'built-in shelf life' and it is garbage right out of the box - right from the start. Drives me nuts - it really does!!
My NAD CD player lasted me 10 years. Seems like NOTHING lasts longer than 10 now, if that. It's ALL JUNK.
Want something well-built? Go to the Goodwill, Salvation Army, local thrift stores, & especially garage sales 7 estate sales. That's where the 'excellent quality' old stuff is, and the 'old stuff'
w o r k s. And it lasts 'forever'
. You can't even get a 'real' pair of pliers that 'feel right' & work hassle-free anymore. The last thing I want to do is do a job and fight or struggle with using the dam Chinese Craftsman pliers from Lowes. It's all just too much. Find a pair of real ones at the Salvation Army or Goodwill, 99 cents - you WIN!!, & they will last FOREVER. Put them in your will to your nephew, and he will use them all his life too.
It's pretty sad really. 
I'm sticking with Vintage Equipment - whenever possible - nothing new. I really do try to Never buy new anymore.
My 2010 'not used much at all' NAD CD player crashed out after 10 years, so after 3 months without a CD player, I gave up and just went to Goodwill and bought a 'like new' blackface Sony CD player for $7 and it sounds 'seriously BETTER' than the NAD when it was new. (I did have to buy a 'like new' remote off eBay for $18. No problem.) I just got lucky on that find. This Sony sounds wonderful and runs totally quiet and smoothly. I think it is seriously like almost new, if not new! Just got lucky. Not a scratch or fingerprint on it. New.
My 1970 Big Box speakers with AlNiCo magnets have worked just finek and sound great for 54 years without any problems. My wife bought a new pair of CVs that lasted 5 years, then the surrounds rotted out. Then I saw the dog piss on one of the woofers, I don't blame him at all, I hated them too, and gave them to my brother for 'whatever' and he used them in his 'bands practice room' for stools to sit on, and they just collapsed - JUNK cabs. The wife then bought some New Bose 701s - you know, she had to have BOSE! I told her - DON'T DO IT! Pure JUNK - and immediately we had problems with 'NO SPARE PARTS' avaliable... THANK YOU BOSE for nothing. You know, it's like -- You Bought them - it's Your Fault, it's YOUR Problem. Bose. Nephew bought a Bose headset, the super think wire broke to the headset - right in the garbage, can't fix it.
You can't even buy a broom that works anymore. Bought a new push broom from Lowes, total Junk, it fell apart, threw it in the garbage. Then bought a regular sweep broom (what could possibly go wrong with that? - it's a sweep broom!) and it lasted, no joke, about '20 minutes' and the handle fell apart. I didn't take it back to Lowes - I should of. Would of spent more on gas that the broom was worth. I'm just tired of taking all this 'broken brand new' garbage back - so I just quit buying most anhything & everything new which is all 'broken brand new' junk. And "don't look back".
Read this and learn: Then there was the New Whirlpool refrigerator - what a piece of NOISY sht JUNK that was. Don't EVER buy a Whirlpool unless you want to live in LOUD NOISE. Got my money back after fighting with them hard for 3 weeks. I wouldn't back off and they gave up - got tired of hearing me scream, and I was screaming!!!!!! And it goes on and on and on. It's all 'Chinese Junk'. It's all 'broken brand new
'.
Then... the NEW 'Trane' Air Conditioner. A $8000.00 seriously expensive ABSOLUTE NIGHTMARE. Unacceptable depression followed. It went BAD. Ended up losing $1500 more on that one. Unacceptable.
Went to my cousin's house. He had an old beat-up well used electric drill his dad had since 1950. It looks old as dirt. Even the 'style' looks super old, like one of the first ever made (which actually really got my attention!!!) I He didn't want it so I asked him if I could have it for remembrance of my Uncle, and he said sure! I plugged it in - Works perfectly/flawlessly - 74 years old and hadn't been plugged in since 1975! The ' REAL ' Craftsman, the real 'stuff'.
The old stuff works!!
Hope someone finds this amusing, or educational.
