The obvious retort is "raise wages", but that's exactly what one of the interviewed businesses is doing:
> The Wacky Knacky Diner in Osage Beach, Mo., near the Lake of the Ozarks, boosted wages to $20 an hour, then added health benefits and a retention bonus.
The article also notes that they found twice as many job listings offering hiring bonuses as compared to a year ago. The market is working as appropriate and the situation is sorting itself out. These headlines are starting to feel like clickbait.
They also highlighted some other temporary and seasonal roadblocks, such as parents being at home while their kids are out of school:
> A survey by Indeed found most job-seekers plan to start working within the next three months, but many are waiting for schools to reopen, vaccination levels to rise or for their personal savings — boosted by unemployment benefits and three rounds of federal relief payments — to run out
The article is worth a read. There's more to it than the "just raise wages" comments.
