How is this not a "failure of capitalism"?
When you start talking about big organizations with tons of legacy rule-making and policy there tends to be a lot of misalignment of incentives that pops up over the years. It doesn't really matter the societal structure.
I'm betting this is a classic "when everyone is responsible nobody is" type of failure you tend to get in organizations that have double and triple redundant rules to prevent failure but no realistic way to do your job without shirking some of your responsibility.
Don't know about those countries but I was in the general geographic area when this accident in Rouen happened, in 2019 [1]. The same as in this case, the main media (i.e. the Paris newspapers) pretty much ignored it, buried it in their 20th page or something, that's when they weren't calling really concerned people out as "paranoids". Luckily for me I was just a tourist in Normandy back then, so I got out of the area pretty fast.
Almost forgot it, Buffett himself was one of the major shareholders in Lubrizol. He even had the audacity to call it just an "unfortunate story" a couple of years later [2]. So, yes, I pretty much regard this as a failure of capitalism.
Later edit: This job [3] of picking up dead fish after an environmental disaster should have been done by a government-run agency. That way they would have correctly assessed the damages, the most likely causes, the compensations for those affected, the measures to be taken so that a similar thing doesn't happen in the future. Instead it looks like a private company has been employed to clear up the mess, in pure capitalistic fashion.
