Well I have a couple of comments for this film, SFA...
I looked at the comments below this video, one of which was "Imagine living in a world where all your clothes and shoes were made locally." Sometimes I think about that now, with our supply lines so fragile and easily disrupted in the pandemic, and maybe that local production is something to aspire to again...
Someone else mentioned all the old people and the children among them, assuming all these were indeed laborers...and I thought of Mary Cassatt, the famous American artist of Impressionism. She traveled to Paris for her painting as soon as travel was safe after the Civil War, i.e. maybe 1865, and painted there until her death, 1926.
I have read that her paintings contributed immensely to the (new) idea that childhood was a special time. Child labor was common, children considered just small versions of adults, and a hungry 12-year-old could be sent to adult prison for stealing a loaf of bread.
Here is one of her mother-child paintings, Breakfast In Bed.
