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.
Fair enough. I see your point and it’s a good one in my opinion.
