Mildly Infuriating

I don't think that's what the graph shows at all. It shows what the average person spends on healthcare each year versus what they get out of it (life expectancy.)

It does so for several countries and shows how things changed over the last half a century. The steeper a line of a country is, the more the healthcare system and medicine has improved. The flatter a line is, the more money you're pumping into the system for less benefit. And medicine should improve. We've made quite some progress since the 1970s and found cures to ilnesses that were a death sentence back then.

That people need more treatment if they're old is a true fact. But it's not really depicted in this graph. Sure it's somewhere in the numbers but you'd need a different diagram for that. Keep in mind that also in the 1970s people grew older and there were old people around... People had grandmas back then. And also people nowadays are healthier for a longer period of time and also retire later. These things work against what demographics makes worse. But it also doesn't cancel out each other. You'd need a more comprehensive study and more number to tell, not just speculation which is most certainly wrong.

But the mere fact that the line for the USA is such an outliar shows that there is something severely wrong with that healthcare system. And you can see when it started and that it steadily continues this way. Either you're a different species and medicine works differently for US citizens than for Europeans, or you have severely unique circumstances in the country, or you're just getting ripped off and some people get rich with the billions that don't contribute towards health.

And that you someday retire and become a burden on the system is how it's supposed to be. That's why you paid all the money during the decades you worked, despite not being sick (yet.)

And there are some more pecularities in the graph. For example you can see that life expectancy is actually decreasing(!) in the last years. That could depict the drugs (Fentanyl deaths) and the rise of suicide in the last years. I'm not sure but these could be possible explanations. Also im Germany where I live mortality rises. Especially during the Covid years and somehow it affects people from the eastern parts of Germany more than people from the western part of the country. That's all not in this graph however and the reasons are complex. I'm not sure what the cause is for the decline shortly before 2018. People speculate it's influenza waves and things like that.
