Hiring rates skyrocketed during covid, but so did attrition rates (well, the same people joining Google left some other company)
After big tech started freezing hiring in summer 2022, attrition rates most likely tanked, people wanted to stay put. 6-8 months later, companies ended up with way more employees than they planned, even though they were the ones hiring, cue layoffs. People will crap on Google or Salesforce "why did you hire so much?" - but during the great resignation - what were they supposed to do?
Gee, I dunno, maybe NOT double in size like Salesforce did?

I believe if you're a US citizen vacationing long-term in France because your work prospects aren't great at the moment - you'll still show up as not in the labor force in the labor force participation rate: https://fred.stlouisfed.org/series/CIVPART
But you won't show up in u-1 through u-6.
> Discouraged workers (U-4, U-5, and U-6 measures) are persons who are not in the labor force, want and are available for work, and had looked for a job sometime in the prior 12 months
And, as you say, there are labor force participation numbers if that's what you're interested in.
