I used to work at Appliance Park in Louisville. ... After transferring from GE Aircraft Engines in Evendale, OH (Cincinnati); it was a big shock to go from aerospace quality to bare minimum quality. At GE Appliances it was "how can we make it cheaper" - not like it should have been "how can we make it better". I will not get into some of the actions that I feel were unethical business practices, driven by the almighty profit. ...
I can honestly say that quality was important to my old mega-corp, even in the lower end consumer product lines. I can't recall anything I'd consider unethical when it came to the consumer (some internal politics got pretty dirty though).
There were debates about the QC group holding the lowest end products to the same cosmetic standards as some new high end product that was still getting very high 'early adopter' prices, but for the most part, a blemish on a low end product would get it rejected the same as a blemish on the highest end products.
One interesting decision was hotly debated, and considered unethical by some - it turns out that there was a point in time when a new low end product could actually be made cheaper by using the new components we used in the higher end products, and these new components were also lighter (these were portable products, and light weight was highly valued). But the product manager wanted more differentiation between the low and high end, so they added
dummy weights to the low end product.
Lots of people thought that was terrible. I didn't, the customer was getting what they paid for - the weight, price, size, performance and features were all published specs. If the customer didn't like it they could buy something else. It was all transparent, so to me, not unethical. But that's as 'bad' as it got, AFAIK. Mega Corp is a shell of its former self, but not because of quality.
[edit/add:] - I now recall that we tracked warranty expenses closely, which were a significant hit to profits. So there was an attitude of 'quality pays', rather than 'quality costs'. But of course there needs to be a balance. And it's absolutely incorrect to think that a quality approach always costs more (even before warranty costs are considered). Often, a cheaper, more streamlined process produced better quality as well. Maybe if those quality metrics were applied to management, Mega-corp would still be a big player.
I do think quality of many items isn't what it should be. I somewhat blame the consumer for that. Many people seem more interested in the latest style and features, and trade in working appliances (or move) before they would wear out. So suppliers respond.
