The time chart below shows the U.S. unemployment rates since 1970. We are at 4.9% right now. That is low, but not as low as the 4% we had in 2000. But if you look back at the 1970s and 1980s, we are still doing well.
But, as my students know, unemployment could be low if there are alot of discouraged workers out there, people who are not looking for jobs (they have given up). They are not part of the calculation of the UE rate. But, in the graph below, the blue line is the labor force participation rate (the % of adults who are working or trying to find work). The pink line represents the % of the adult population that have a job. Although not as high as around 2000, both of these numbers are higher than for the 1970s and most of the 1980s. So alot of people are trying to find jobs and alot of them do have jobs, by historical standards.
