HR Tech Companies are Solving for 2021 Problems not the Future

I am seeing many companies that appear to be solving COVID-era stimulatory problems around people. Such issues include employee recruitment, training, and engagement. These solutions are all tied to solving the great resignation problem that seems to be affecting many industries.

I am having a hard time understanding this labor shortage issue. I also do not feel like digging through data to understand it. The scenario reminds me of Avengers: Infinity War where Thanos snaps his fingers, and half of the world's people disappear.

Are these problems going to be around in 2024 if the economy contracts and inflation is still out of control? It seems hard to believe that people are going to not want to work when bunny bread is $4/loaf.
