The main problem is that most business are run by people who have no believe at all that you could run a successful company without tricking people into buying your product. That means they don't even try. The rare exception are companies where rhe founder is e.g. a principled engineer, or some German family business that does nothing but ball bearings in the 4th generation and their business model is basically to be the best at ball bearings. Something like that.

But so many publicly traded companies appear to basically have become stock gambling dens that accidentally produce some products on the side out of legacy reasons.

Many are of the kind that use quality only as a marketing statement and when it comes to the engineering choice they will not even shell out 10 cents more for stainless screws to hold the thing together.

The reasons why there is little quality products is because the incentives all point in the other direction for most companies. And where they don't it is usually a special niche product or the intrinsic values of one or a few individuals making the choice to put their ideals above their wallet.

If we want this to change we have to change the incentive structure.
