Since we now know that Covid can lead to long-term suppression of the immune system and that a significant part of infected people have other lingering issues, this is obviously false.
> Unlike in the pandemic’s early phase, these deaths are not primarily among the old. For people 65 and over, deaths in the second quarter of 2023 were 6 percent below the pre-pandemic norm, according to a new report from the Society of Actuaries. Mortality was 26 percent higher among insured 35-to-44-year-olds, and 19 percent higher for 25-to-34-year-olds, continuing a death spike that peaked in the third quarter of 2021 at a staggering 101 percent and 79 percent above normal, respectively.
Indeed, that suggests they are correct - unless you have a better explanation of why older people are doing better than pre-pandemic.
It's likely just a matter of being unlucky this time that a well spreading virus stumbled upon this way of avoiding immune system which breaks it.
A bad case of Ebstein-Barr virus (a herpesvirus, causing mononucleosis) can set you down for life, for example. Certain bacteria like ones causing Lyme disease can do it too. You don't hear it talked about because they do not spread as readily.
> To some extent, we know what is killing the young, with an actuarial analysis of government data showing mortality increases in liver, kidney and cardiovascular diseases, and diabetes. Drug overdoses also soared nationwide, but not primarily in the young working class.
Edit: and the table on p43 seems to directly contradict their claim that the excess deaths are concentrated among the young "working" as opposed to non-working: Age 15-44 have almost the same percentages (18.9% vs 19.2%) for excess Q2 deaths; the insured cohort is the slightly lower one. "It's probably mostly drug overdoses and COVID" still seems like a reasonable null hypothesis to me.
