That makes it a less useful statistic for talking about problems around unemployment. I think that's why the BLS has so many different measures of unemployment.
If I had enough money in the bank to live the rest of my life comfortably, there's no way I'd be employed.
“Unemployed: People who are involuntarily out of work considered as a group.”
I think it’s misleading to classify these people as unemployed, since many of them choose to not work. If they wouldn’t have had a job anyways, it skews the statistic.
Well are they employed by anyone? No. So they're unemployed. It's perfectly valid to be unemployed while studying... but you're still unemployed.
