It could be the case that Americans have a bias towards seeing calamity instead of tragedy (that rings true in my opinion), but I don't think that bias is evidenced in you or other modern English speakers treating the two words as synonyms.

There's a difference between saying someone is responsible and the victim is responsible.
The Cargo Cult decries the principle of legitimate responsibility, and consistently attempts to deny the guilt of the true architects of tragedy in numerous ways - victim-blaming being a very popular one.
In this example, a significant number of Americans would rather an adult woman die in childbirth than terminate a dangerous pregnancy.
If adult women - who may well be married and have a family - actually do die because legal abortion is unavailable, those Americans become responsible for avoidable deaths.
But the magic of the Cult's moral inversion means they continue to consider their position a wholly good one.
"Good intentions suffice."
This is not the same as - for example - a climate denialist buying beachfront property in Southern Florida and then being amazed when it floods in a storm and becomes impossible to sell.
"Consequences are things that happen to others."
These look opposed, but the MO is the same in both examples. Legitimate responsibility is denied, and replaced by a simplistic self-affirming moralising certainty which is actively hostile to mature empirical rationality and empathy.
In retrospect I should have chosen a less sensitive example, so I'll do that now: In the common modern sense somebody being killed by a falling tree branch is more tragic than a drunk driver fatally striking the same tree. But in the more traditional sense of the word tragedy, that's flipped backwards.
Now that I think of it though, even in this other use implying a flaw, you are supposed to relate to and sympathize with the flawed character. In this view it seems harsh and inhuman to complain that every calamity might be seen as tragic. A mature person can often sympathize with human suffering even if the sufferer did something "bad" to get there. We shouldn't be 100% in punishment mode or gloating at comeuppance. Forgiveness is a thing. Sympathy for imperfect people is also a thing.
If this effect is real and not something I'm imagining, my best guess is that it's a result of much wider exposure to language (consider: how many fewer words, spoken and written, did the average person in 1850 hear or read in an average day, than you do?) with the bulk of it coming from writers and speakers far less well-educated, on average, than the people who had access to, say, publishing in the 19th century or perhaps early radio, and so more likely to mis-use words or phrases. Mistakes have always become common usage if they live long enough, but if the rate of mistakes become very high and the ability of those mistakes to gain a wide audience grow, that must surely have some effect on language, and any notion that it must necessarily be neutral or even beneficial strikes me as wishful thinking—I believe it's at least possible that changes of this sort would harm the practical expressive potential of language (as when we here judge that this useful word's distinct meaning is dead, to no purpose, and without ready replacement).
Languages lose complexity all the time. Ask Italy, Spain, Portugal, France why they don't have a full Latin case system with various suffices to distinguish them. It's not because their ancestors suddenly became stupid. It's just that languages change and a very common outcome is that complexities get lost in time. I can tell you with certainty that this has been happening in Indo-European languages for thousands of years and yet civilization has thrived in the same period.
You're overthinking it in a very judgemental way.
This strikes me as a perfect illustration of the article's point. The US spends more on healthcare than any other country in the world, yet our maternal mortality rate in 2010 was higher than "nearly all European countries, as well as Canada and several countries in Asia and the Middle East" [1]. As of this year, the rate was more than double what it was in 1987 even as it declines in the rest of the world [2]. Black women's maternal mortality rate is three to four times that of white women [3].
In spite of which it would be "deeply offensive" to insinuate blame here, or that there may be structural and cultural causes that we refuse to see or fix. "Tragedy is a synonym for calamity", indeed.

They would not find fault with the statement because, particularly in the USA, they will indeed consider it a tragedy and that there must be someone to blame.
