Yes, I think we are in general agreement, so I then ask what is the Pope’s point? Where is his nuts and bolts solution that can applied, especially in parts of the world where the level of safety he believes should be achieved is unaffordable? In this particular case, you accurately lay fault where it belongs on the owner, but for the Pope to extend this to some characteristic of capitalism, is also wrong, as you point out.
Socialism gave us Chernobyl. Socialism built those paint factories my friend is trying to fix in China, each one a potential death trap. Socialists can be moral too but often put power into the hands of people with no practical experience. These decision makers are just plain stupid but they are loyal, and that counts more than competence in a socialist system.
If the Pope wants to talk about moral business practices, he certainly can and should do so but to attribute them to capitalism smirks of an endorsement of socialism, which has killed far more people exclusive of industrial accidents.
I’m not entirely sure the pope IS ‘attributing to capitalism’ this particular tragedy - he doesn’t use the word, only the article writer does. His comments on ‘slave labor’ and on ‘focusing exclusively on .... personal profit’ appear to refer to the way these particular workers were treated and ended up - i.e. dead, through their employer’s lack of morals, pursuit of short-term profits by criminal means, and industrial malpractice, in a situation where many of them likely had only two life-choices here - take this job or life in abject poverty. This is what, to me, he is commenting on - moral practices in business. Which is quite different from criticizing capitalism per se.
As for applying ‘nuts and bolts solutions’ - this is perhaps more of a political issue, specifically one for the Bangladeshi government, as I think you yourself stated. I don’t find it particularly odd or unacceptable for a Christian religious leader to comment on the moral dimensions or implications of a particular newsworthy incident. It does seem to me - from what is quoted here, anyway, and admittedly the full text of the pope’s comments isn’t included - that it’s the writer of this article, more than the pope, who’s making the papal comments out to be a criticism of capitalism itself.
