"Burn , baby , burn" "Drill, baby , drill"
Things won't be made to last or be repairable , that would interfere with the present business model (consumerism + growth ).
America has to surpass China in both fossil fuel use and "alternative" labor. the 2nd industrial revolution "frack , baby , frack"
pump the toxins into the shale - become the greatest user and producer of fossil fuels the earth has ever seen.

Just like Hurricane milton (below). Sucking on the abnormal 32C gulf to level Tampa. Red dot is continuous lightning (160m/240khr ++++)
We can "weather this", just relocate to the slave labor valley (Tennessee).
Just a small price to pay for "drill , baby , drill" oh , well !

Well, it is true than in Barcelona and Marseilles they got Chinese Quarters.... but that was because at one point, some Chinese guy with Marco Polo got lost on his way home and spent some time by the port waiting for a ship to go home.
"Hey, this is the Chinese guy's quarters"
"Oh, yeah, the Chinese Quarter"
There are quite a few Chinese living there nowadays. Nothing like meeting ethnic Chinese that speak Catalan and Cathtilian with a lisp.
My objection to your whole line of reasoning is that you are accusing perfectly legitimate businesses, such as Madisound and Parts Express, to be guilty of using "snake oil" to sell their products.
And that is nonsense.
These businesses are representing and promoting the products they sell according to the manufacturer's specifications.
There is no "snake oil" involved.
No I'm not ! But they do "go with the flow" and incorporate subjective audiophile fallacies in their product line.
50$ "Clarity caps" take advantage of disinformation.
On my PPM "Wolverine" amps , whether you use the "$50 clarity cap" vs a quality $2 wima poly 4.7uF at the input would make no difference.
I went with the flow to actually design for a "audiophile cap" - I actually support some audiophile fallacies. Big caps look cool , I'm not buying them.
Maybe the fact you spent 50 dollars on a cap would bias you to think you had better fidelity ??
I suppose this "value added" version of a scam is valid. If you market something right , it will sell.
The psychological perception of a product can outweigh it's real merit.
As far as legitimate , in "scamerica" , anything goes !
"Snake oil" to some is scripture to others.

I actually agree with a lot of what you said.
And certainly, Madisound and others have a lot of very positive descriptions of their products on their websites.
Whether those descriptions really reach to the level of snake oil or not seems to be a personal opinion. In mine it does not. Just a lot of typical hyperbole that I would expect. But not at the snake oil level.

Well if people think they need something.
Rational or not.
It makes sense to sell it.
They are gonna buy it regardless.
Some people actually need 400 to 600 watt crossover parts too.
If they wanna buy huge magical coils and caps
for a 60 watt system.
Well, we sell those too.

Not going to happen but exactly the solution. But what about the people earning their money by producing, distributing, being middle men?
It seems all can be simplified to the consumers wanting too much stuff and also being manipulated that having stuff is happiness. That greed model is more or less successful in various societies (in some areas people rent space to put away their excess stuff) and finding stuff built to last is hard. We can blame China, the USA or whatever but all those legitimate businesses together create the issues because we keep buying and replacing stuff. Consumers also accept that stuff is defective in a short time or that their phone can't be repaired with a new battery. And when stuff is repaired elsewhere continuous warnings appear in the screen that the battery/screen is not original...
Simplifying further one could say that there are just too many mouths to feed worldwide. Every new citizen will do/need/buy the same as the others and we can't go back to the simple model with so many people. Birth control might be the only way to brake the circus truck.

And Ebay.
Same exact 317 regulator with led display and "banggood" capacitor. drop in a few Nichicon's , perfect 1A PS.
Actually a little cheaper than the 10-12$ ebay price.
I guess the same backroad board house sells to all .
Seen the same product on ebay,walmart,amazon,temu. And even cheaper on Alibaba ! If I buy 100.

Yeah , I have quite a few "banggoods" , use them for my breadboarding. NOT for any final product.
"ChangQ" is another dubious cap.
I got screwed by both Temu and Ebay .
(below 1) TEMU $6 LM317 cheapo kit , worked < 200mA. 317 dropped voltage @ 500mA - Not a 317.
Most likely a 317LZ repackaged in a TO-220 case. It adjusted down to 2.6V like my real LM317lz's , no "Juice".
SCREW temu for any electronics.
(below 2) Temu has these , Ebay has these. Must be legit , It will happily run (12V) all day with 10R , lose .02-.03V (1.2A).
I have 3 of these , One did not have "banggood" caps !
(below 3) I am pissed !! Bought a LT1083cp. Would not adjust below 5.1V , advertised as 2.5 -30V. Hmmm
Has big 7A diodes and a 7A poly fuse. Most I could get was @ 2A before the voltage collapsed !
I think this semi is actually a repackaged LM7805 in a TO-3P case and they designed a PCB to make it adjustable.
#1 is not worth my time. (screw TEMU) - #3 I'll either get my $$ back or tell the seller to give me a free #2 , which I know is legit.
Buyer beware , there is NO honor anymore....
PS - #2 you don't get Sanyo's ..... you get "banggood" - banged good.

LT1083CP is one of the most copied regulators since it went out of production. Both LT1084 and LT1083CP apparently have a magical status with chinese DIYers.
All the stuff you show seems a waste of time and resources. Even if they do work they don't have known quality electrolytic caps and they don't meet expected specifications.

True ! Now I can just totally write off these cheap Chinese redistributors.
In fact , the 1083 experience will make me just design my own PS , and make custom boards.
What's on the market is so inferior to even one my drunken designs , I'm amazed.
Do they think (we) are foolZ ? They are right , most N. americans know how to pop pills.
BTW , your reply also seems to be a waste of time and resources.
EDIT - I don't have to reply , the open source AI running on my video card is writing this.. ha ha.
AI soldered those kits together , as well. AI also figured out legacy darlington idiot amps and extracted
hidden knowledge. ALL HAIL - to AI , YES ....

Finding a real LT1083CP is quite hard. I had trouble finding original LT1084 in the superior TO-3P package but found a full rail.
Yeah buying such stuff and talking about it is a waste of time and resources and just clutter in a home. Shortest path is a good design and parts from distributors. For just 1 device that will actually be used. These websites feed the human tendency to be greedy and feeling/thinking that material possession is happiness. It isn't, it is sad.

I will just make my own $hit , I no longer trust the supply chains.
I HAVE the proper parts , I just wanted to see what the pubic was exposed to.
I am VOGEL , I create my reality.

The problem is, it changes an awful lot of things. Does that mean going back to through hole components? Or just doing pluggable boards?
Does replacing all the internal electronics count as repair?
We need a definition of repair....
If my kitchen scales die they'd be expensive to repair because labour is expensive. Do we artificially inflate the price of a replacement to 'encourage' me to get it repaired?
How do we persuade someone to either keep parts inventory or manufacture parts for a couple of decades.
I know how this used to work in my parents time, but I'm not sure there's a clear & implementable path back to that state without also sacrificing an awful lot good stuff.
It used to work like that. The extreme other side is throw away stuff. Now we can settle in the middle if we want. Produce stuff in our own country again and create local jobs for instance. Nobody forces us to buy throw away stuff produced far way but yet we do. Eventually leading to own economic misery, not enough jobs and dependence on china for literally everything.
Don’t know the definition of repair but I do know most throw away stuff to be constructed to be irreparable either economically or hardwarewise. Not very green.
What happened the last decades also changed an awful lot of things. That I can’t have a battery or screen of my Iphone replaced locally with second source parts for instance. The right to repair should be defended IMHO.

We do it, in part because labour's cheaper, or more permissive (you try getting permission to build a big factory in the UK) or for the old reason, it's where the raw resources are.
In any event, it would mean more expense for us as consumers. Can the UK really have it's own large scale semi fab plants so we don't have to buy from Taiwan or Indonesia and manufacture at the price they do there?
There was much fuss recently in the UK on the conversion of the UKs last steel smelting plant. Many complained that this would mean the UK was dependent on imported steel. But none of them seem to be aware that the ore and coal were both shipped in from abroad. There is a sense in which for many countries you're just going to be moving your dependencies elsewhere in the chain...
