You mean of the 10.1 millionaires in the US right now? I’d say the vast majority of them. Of the 492 billionaires in the US, probably not as many but since I have no Idea how the typical (Is there such a thing?) billionaire lives I can’t say for sure.
While it’s a bit of a pain to navigate, the Bureau of Labor Statistics is your friend when you want the real answer.
The U6 number is 7.6% which is the lowest it’s been since 2001. (Caveat: It’s been trending downward since Mar 2010 when it reached a peak of 17.1%)
The workforce participation rate has been flat, bouncing around 62.8% since summer of 2015 when it bottomed out at 62.3%.
You can get these numbers for yourself (I recommend it) they’re publicly available on the BLS website.
