Have you all never heard of triage in emergency situations, saving the less severely wounded, women and children on lifeboats, etc? Have you never spoken to older relatives who expressed their willingness to sacrifice from their already well-lived lives so that younger generations can lead full lives? This isn't a zero-sum situation, but it's not an infinite range situation either. There are many reasons that "years from expected life" is the most valuable metric in measuring loss from the pandemic.
Yes, on a macro/societal/evolutionary level, young lives with productive/reproductive futures are more valuable than older lives. We have sacrificed a massive amount as a society to protect the vulnerable for two years now. Thank god most are now vaccinated (as am I) and largely protected. A competent society can and must have the conversation about when the negative effects of our sacrifices on society at-large become too great. We are seeing that conversation forming right now. Your either insincere or underthought moralizing will not change this.
There's a gross irony to so many advocating for near-eternal life through not living at all. Let the kids play - let the resiliency of mankind shine through the darkness to provide joy and hope to so many.
