Labor Day was established in the latter part of the nineteenth century* in recognition of laborers. It has become a holiday, presumably a day in which the laborer can lay aside the burdens of his work for at least that day.
Here's an irony. Now we have that probably one-quarter of all laborers in the US work in retail concerns. Retail sales on Labor Day have become such a large part of the industry that the day is second only to Black Friday in dollar volume.+ Now who makes the transactions? Why, the laborers who work in retail. And not only do they work on this, their holiday, but many of them are required to work extended hours!
Happy Labor Day, y'all!
+Or so I read somewhere.
