What happened to the "good jobs"? A look at the decline of jobs that supported middle class life

The number of unemployed Americans looking for work has plummeted to pre-pandemic levels, according to the U.S. Bureau Of Labor Statistics.  

But workers are also quitting in record numbers. Job opening reached a near-record high with businesses looking to fill a record 11.1 million slots, the Labor Department said this month. 

Some experts say it is a sign the U.S. has plenty of jobs — just not enough of what many would consider "good" ones.
