The numbers they usually use for unemployment don't, as I understand it, include all those who have given up looking.
There are a handful of different employment figures, all generally abbreviated "U" and a single-digit number, and I can never remember which is which but there's one which more accurately represents what we think of when we think "unemployment", and it's not the one that gets reported.

I found this chart here with explanations. https://fredblog.stlouisfed.org/2015/05/the-many-flavors-of-unemployment/
According to any of those measures our recovery LOOKS good, all those numbers are back to where the were before the recession.
What's off about the country isn't being captured by any of those employment numbers...
