Sometimes the truth is literally hiding in plain sight. A good, bias-free way to examine the supposed lifesaving effects of a policy would be to look at excess all-cause mortality or its inverse, life expectancy. That gives a clear picture of the "final bill" of net effects, regardless of the "why" behind it.
For example, a
recent article notes how life expectancy in the USA has lagged behind that of practically every comparable country in the world, in both absolute AND relative terms. America is clearly an outlier, and not in a good way, despite being the richest and most powerful country on Earth.
So what gives?
Is it Covid? The collateral damage from lockdowns? Or the vaccines? While things clearly deteriorated further during the pandemic, and especially after the vaccines were introduced, the diverging trend in life expectancy began well before that.
Is it fentanyl, or the opioid crisis more generally? That's a big part of it, and something you really don't see nearly as bad anywhere else in the world, but the trend pre-dates even that by quite a while.
Is it illicit drugs in general? Partly, but those "epidemics" ebbed and flowed repeatedly while the divergence continued regardless.
Is it tobacco? Well, as deadly as it is, given how Americans generally smoke less than Europeans, and always have, that cannot be a significant reason for the divergence.
Is it obesity? Partly, but several other countries are also catching up to us in that regard, so that only explains a fraction of it. (And why are we so fat in the first place?)
Is it poverty? Lack of healthcare? Inequality? Or any other adverse effect of neoliberalism? Very likely at least part of it. After all, the American life expectancy began diverging from peer countries in the early 1980s during the "Reagan Revolution". Before that, it was well within the normal range of wealthy countries. But not even the UK under Margaret Thatcher could deteriorate quite like we did.
Is it guns? Partly, but again that only explains a fraction of the trend, and there were already plenty of guns in the USA well before the divergence.
Is it traffic deaths? Getting even warmer. Traffic safety has clearly lagged behind the rest of the developed world indeed, and it's not only because we have more cars either.
Or is it perhaps the pink elephant in the room? That is, Americans drowning themselves in the bottom of the bottle? Yes, and we are paying a heavy price for it: alcohol is indeed one of the largest contributors, that actually
kills more Americans than opioids and all illicit drugs
combined. Let that sink in.
Along with suicide and drug overdoses, alcohol-related deaths are in fact one of the most common types of "deaths of despair" in this country.
So to those who support the 21 drinking age, riddle me this: if your beloved policy saved so many lives on balance like you claim, why did America's life expectancy lag behind all of our peer countries that generally did NOT raise their drinking ages any higher than 18? And why are alcohol and traffic deaths such large contributors to the divergence?
Take as long as you like with your answer.
And bonus points for those who loudly cry "think of the children!" when it comes to public policies they dislike, and are still able to somehow explain why American infant and child mortality is so much worse than peer countries as well.

UPDATE: But don't European countries supposedly have higher
liver cirrhosis death rates than the USA? Well, some do, but many countries are the same or lower. The UK, for example, used to be higher, but by 2016 it was lower. Canada, Australia, and New Zealand also have lower cirrhosis death rates as well.
