The economics are simple when you know and understand the main driver, but its inconvenient, and there are entities that want it hidden, because you have bad people doing bad things, and wanting to hide those things, and historically leftist leaning places/people do all of the above to a greater or lesser degree rather then engaging in actual truth telling.
The simple fact, that will probably get your post downvoted to remove from view, is this reduction of quality is driven by fiat money-printing.
It may be non-reserve issued debt (Basel3), or government subsidy, or contract. There are many sources, laundered, and the economy for the most part today has been silently nationalized, which is why it fails. Bailout is required to overcome the end of the boom/bust cycle and continue forward for a time thereafter, it happens cyclically (a true-up, the difference between actual production and fraud/loss) and it requires exponential amounts each time which are taken from every person holding money. There have been at least 4 instances that I can see where this has happened since the 1970s changeover to fiat (de-peg from gold/petrodollar).
The inflation/debasement in purchasing power causes companies to debase their product, to keep up with the escalator of inflation to continue on moving forward. This is worsened when you have foreign entities using slave labor through controlling their own currency, to destroy domestic business; such as manufacturing over a long period of time.
There is obviously an objective point where eventually that can't continue, because the economics of money-printing fail, but that point is what many leftists knowingly or unknowingly aim for; the ones that know just don't want others to know the emperor has new clothes because knowing and communication of that knowledge allows reaction and adaption, and there are some people who believe if an individual can't express words, or convey meaning, then that negative behavior associated with that conveyance (in their deeply flawed perspective) doesn't exist, and they can make people better that way.
The strategy for doing this is through sieving and concentration of resources into fewer and fewer hands, while retaining control of such resources. The lead market players today based in money-printing can control and continue operating because of their preferential banking ties, while competitors cannot enter or compete in the market because the market no longer meets the conditions of a market. Namely adversarial price discovery which requires visibility, and non-cooperation. Money-printing/banking isn't given for free, it forces many entities to cooperate; and adversarial independent decisionmaking is needed for economic calculation. Mises wrote about this extensively in broad strokes. There are quite a large number of impossible hysteresis problems that mark the system the boomer's pivoted to as unsustainable, hyperbolic, and inevitably fails to impossible to solve hysteresis problems (where knowledge of a state needed to react doesn't provide sufficient time to change course because the effects precede that knowledge).
Artificial distortions, trending towards chaos will grow and self-sustain, eventually causing whipsaws that cause it to fail, but that takes time since the point of failure is stage 3 ponzi, where monetary properties lose all value seemingly overnight. Where objectively, outflows exceed inflows.
This is what also drives enshitiffication, why the business growth curve is an S adoption curve (following ponzi), and the inevitability of consolidation/hostile takeover.
The leftist connection is the strategy of sieving, you have to concentrate wealth in few hands first before you can seize it from those hands, and this is what the Fed has been doing. A gradual fabian-based induction to non-market socialism, while ensuring the political power base remains through bad actors that call out other bad actors decrying the public, and others in the group instigating and inducing bad actions while undermining, subverting, and making the resilient system brittle, at every point. Destroying the rule of law through shock doctrine and demoralization up to just prior to bringing it to crisis for the seizure, and re-normalization where either a socialist/communist takeover occurs, or when that fails; a rise of fascism to power. The same regime-change plan that all governments use (give or take). Also, the same driving dynamics that led to Hitler's rise to power.
Jamming communications so people don't catch on and can't react is part of that plan, which is why you have so many bots running around, and the platforms are complicit with the same people as those who want to enable this. Jamming doesn't work without the plausible deniability of karma systems that allow the platforms to grant moderator powers to a large group of sockpuppet accounts (sybil attacks), controlled by a surreptitious moderator. Who may also utilizes many psychological blindspots we all have to manipulate, and damage readers through structured distortion of reflected appraisal (or narrative control, memetics, or belief contagion to the layman, which includes Le Bon's works as a basis).
People are easily manipulated when they don't know the mechanism behind the how. Cialdini in his book Influence touch on the foundations, except reflected appraisal, but to understand distorted reflected appraisal you have to understand how torture works, and what it is really, and if you knew you would see it in almost everything today.
Torture is the structured imposition of psychological stress in sufficient exposure to cause involuntary hypnosis.
Your stated suspicion is a well crafted induction of a common lie that's been repeated so many times, many believe its truth, but it fails under close objective examination.
If the lie were true, you would have competitors coming into the market, and staying in the market; but its not because of the asymmetrical connection to a money printer; directly or indirectly.
Lowering prices below market value to drive competitor companies out of business has occurred in many places where a leveraged buyout or hostile takeover wasn't possible.
You need to operate on debt to compete, but in so doing you become food for takeover, until the parasitic nature has nothing left to eat. That hasn't happened yet, but its probably going to happen in our lifetime. These dynamics in the historic lifecycle is what is driving the adoption towards BRICS, and the chaos we see everywhere.
Eventually you get to a point where everything breaks, and you've been trapped by decisions your parents or grandparents generation chose through aggregate.
Decisions that result in worsening conditions, and your and your family; and their children's futures, being collapse into violent law of nature, or submission to enslavement and a life of suffering before death.
Either result in a loss of control from the choice upfront, that decreases until a point of no return, after which the dynamics cannot be stopped, but you can get out of the way, it just requires a ruthlessness, education, and knowledge that has been deprived from nearly everyone raised in recent generations today. Lone wolves die because they are weak, the movies promoting this concept are (5GW).
