The reported U-3 unemployment rate is measuring the rate of full-time job loss in the economy. That makes a good barometer of the economy as it can describe if job losses are accelerating or not.
You can pick any of the alternate measures and they all say pretty much the same thing. But by overlooking those who have dropped out of the labor market, the U-3 focuses more on what is happening with the labor market now not several years ago.
You can try this for yourself by plotting the U-1 through U-6 rates on the same graph and picking the one you think is most useful as a snapshot of the labor force. You'll probably land on the U-3 as the U-1 doesn't show upticks in unemployment very well and the U-6 muddies the severity of upticks in unemployment. The broad strokes will be the same, but the nuance is missing.
I think this is a perceptive statement; U-3 is most like the derivative of unemployment, so it's sensitive to changes, but not to steady-state issues.
We should probably look at U-6 to help understand where we stand long-term, and U-3 to get a glimpse of whether things are getting better or worse. Unfortunately, I don't think many people want to think about these issues separately, so they'll only want one number.
Third world conditions are much worse than that. I've seen families sleeping on sidewalks. No car, no health care.
Sure everybody wants more. There are a lot of retired people who would like a job, but that is as much about the social connection as money. There are also those who lost their money (scams target retired people) and need a job, but that isn't most of them.
My father turns 70 in three days, and he has struggled to find long-term work for the last ten years. He'll work for a year, search for work for 15 months, work for another 18 months, etc. He would like to be working now, but COVID-19 probably marks the end of his working days forever.
He's been counted as retired a few times during the last decade, though he never was until this year.
At least twice in the last decade, he's been unemployed so long his benefits ran out. Perhaps the label in that case isn't "retired," but he wasn't counted as unemployed, either.
The BLS tracks six measures of unemployment rate via survey called U1-U6. U3 is the official unemployment rate, but they report the others as well[1].
For U3, you are considered unemployed if you do not have a job, have actively looked for work in the prior 4 weeks, and are currently available for work. U4 is that plus anyone who wants a job, but gave up looking because they don't think they will find one. U6 adds in people who only have part-time work but want full-time work.

They basically survey 60,000 people and ask a specific set of questions to figure out which "bucket" people are in.
Because they still need to find work to live, pay heath expenses, and so on, and can barely make it in third-world style conditions without it...
