There are a lot of questionable assumptions used to calculate unemployment which in the past didn’t matter as much as the was a large manufacturing base in the country which is no longer there. The available work is not service oriented especially in retail and food service which are no the only places many people can find work. The problem is this work was never meant to be the primary source of a families income. Hence the drive to raise minimum wages which makes things worse as that forces companies to automate to hold costs down.
