The people who died would have mostly been retired or lower productivity. Shouldnt impact labor costs much. Age pyramid definitely would though.
Note: most of those long-haulers have recovered, but I suspect that a great many of those didn’t recover back to their original job. That means during the time they were disabled, they had to be replaced, possibly at a higher wage.
