Do perpetrator walks when they arrest white collar criminals who helped burn to death humans.

aren't really crimes, y'know--"Corporations Are People, My Friend" except when crimes are committed--then they are abstract, impersonal legal entities that HAD to break the law because their prime directive is maximizing shareholder profits.

Or some such gobbledygook that they tell us to ensure that no one goes to jail.

The money grubbers have convinced enough of society that profits and corporate rights are sacrosanct.

and all is forgotten.
Personally, I'd like for the death penalty to be a thing for companies if their business practices kill people. If through knowingly neglecting safety issues a company kills someone in order to make a profit, the execs would get jail, and the company would cease to exist. All of it's assets would be sold, and all money would go to the families of those killed.
You want to avoid this happening to the company you own, don't JUST follow the law. Make the safety and health of your employees and customers your #1 thing, with profit be a close second.

and there is no inherent reason why what you lay out couldn't happen, except that the ideas and perceptions of most of the U.S. population have been carefully and deliberately nurtured to believe what the corporations want them to believe. We are the most heavily propagandized nation in the history of the world, and it shows.

Just like why should labor be taxed at a higher rate than capital, why should we squander money on the war machine, etc. etc. etc. Because the populace has been brainwashed to believe that we have to.

Which is why the GOPee wants to further destroy public education, and why right-wing kooks are against teaching critical thinking skills and having an educated citizenry.

They want the peasants stupid, uninformed, and hence easily controlled.

Speaking just of the American Construction process, here's what could have gone wrong:

All the members of the project team (sans Owner) have a responsibility to identify that this product should have been disallowed in that application.

If the FR model was specified by the Design team >30 meters, it should have been identified in the Permit Review as disallowed (flame spread information is required). First line of defense.

If it was Substituted during construction by Contractor team, then there will be a paper trail of that approval, and the subsequent Submittal approval. It is a very specific process in Division 0 of Specifications. The architect, contractor, and owner will have signatures on that document. Often these decisions are driven by expediency and money. But that's the 2nd line of defense.

After that, the only line of defense is the Building Inspector and the Fire Marshal, to recognize that "Fire Resistant" is not the product allowed >30 meters (and that is one very misleading product name), and instead know that "A2" is. And the Fire Marshall might not even come on site until that product is installed.

At this point, I'd lay odds that the FR was used in incompetence, not in malevolence.
