Vox's headline is ridiculous, but the study in question is pretty neat. https://www.aeaweb.org/conference/2019/preliminary/paper/yyS... (pdf warning)

They show that even within a specific (job-title, company, state) tuple, higher unemployment led to higher skills requirements, in a probably-causal way.

That doesn't mean the skills gap is a lie, or any other nefarious bad behavior on the company's part. The study doesn't go into that.
