This is likely satire along the lines of https://en.wikipedia.org/wiki/A_Modest_Proposal. The main giveaways are the directness of the language and the time of writing (on the tail of covid when people were unironically making such proposals).

>on the tail of covid when people were unironically making such proposals

They were? I remember a lot of awful stuff about those years, but this isn't one of them. I remember people making somewhat mean-spirited but understandable comments about (some) older people getting killed off by Covid due to their own actions (refusal to take the threat seriously and take precautions, leading them to catch it, and then have much worse outcomes due to the fact that the disease was much more deadly for unhealthy and older people).
