I have to be honest that I'm confused by the comment, too. Including the edit about how being out of work would be traumatic, as if losing a job was unique to the United States.
Where I live, your employer basically has to give you notice (weeks to months, depending where you live). It's common for that notice period to turn into "garden leave" though, i.e. get paid but don't show up.
Mass layoffs, or RIFs, operate under slightly different rules, but I still saw a stark difference between US and EU employees when I went through one at a different corp.
US accounts were deactivated same day. EU employees were given until end of week to look over the proposed terms etc.

My point was that going from (let's say) 'employed, productive member of the workforce, with social relationships at work' to 'sitting at home collecting unemployment' with no transition, no coaching, in the scope of 5 minutes seems like a traumatic rupture.
(I'm not saying I _know_ better, just how I think I would _experience_ such a thing.)
Losing a job happens everywhere, but there are different ways to handle it, I guess.
