the story is that a bunch of workers were offered one denarius for working in the fields. some of them started at dawn, some of them started at around ten, others trailed in toward the end of the afternoon. then the landowner came out and paid everyone the same exact thing.
one read of the story is that life is not fair. okay. that’s basic.
second way to look at it is this: it’s the landowner’s right to do whatever he wants to with his or her own money. he/she doesn’t really care if you got up at the crack of dawn. someone else can come in at three-thirty and pick one grape. landowner pays them, too. shut up. it’s none of your business.
