One of the things I find interesting is the Smokestack Twins, and their different reactions to Sammie’s musical talent. Stack is amazed by Sammie’s talent, but also sees an opportunity to make money. Smoke, on the other hand, acknowledges Sammie’s talent, but discourages him from playing the blues, and instead insists that he play church music, and even threatens him if he doesn't stop.
I found it interesting because Smoke is undoubtedly a staunch capitalist. To him, money is power. He teaches a little girl to negotiate for a higher price, tells Annie that her currency can’t be spent anywhere, and seems to be ready to rough up an old man who can’t pay for some corn liquor. Stack is willing to cut the community of sharecroppers some slack, they work hard and deserve to play hard, even if they can’t necessarily afford it. Smoke not so much. To him, this is business. He doesn’t care, if they can’t afford it, that’s their problem.
“I ain’t never saw no roots, no demons, no ghosts, no magic. Just power, and only money can get you that.”-Smoke.
“We takin cash U.S motherfuckin’ dollars.”-Smoke.
Make no mistake, Stack loves money. The Juke Joint was his idea. He buys a Sawmill from a Klansman. When Smoke says they should postpone, Stack rejects this and says they have to open that night. Stack seems to be a bit more understanding of economic inequality and the people side of business, building emotional appeal, he's more lenient with the patrons. Excited after Sammie belts out a tune, Stack is excited about Sammie’s talent. He sees his music being a profitable act at Club Juke.
“We gon’ make some money!”-Stack.
The twins paid Hogwood in cash, yet he still planned to murder them, as he had purchased a "killing floor". This would be implied to be a scheme that Hogwood was running. Ironically, at the end of the film, when Hogwood offers Smoke money in exchange to spare his life, Smoke kills him. Smoke was dying, whatever money Hogwood tried to offer him, was essentially useless and had no power over him, and it didn't protect Hogwood.
He nods to the premise of the juke joint, a place where Smoke and Stack could build wealth off of their community’s need for release. “It’s not the vampires doing that; the vampire is not charging anybody money for a feeling,” he says. “I was very interested in the twins. If the vampires never showed up, who are the vampires in this movie? Who was the first person to recognize Sammie’s gifts and see some money? Who’s scary? Who’s everybody afraid of in this movie?-Ryan Coogler, Rolling Stone.
