in little shop of horrors, the song "don't feed the plants" is a metaphor for not buying into the capitalistic system
audrey ii is a metaphor for greed, yes, but he's also a metaphor for taking advantage of the people around you so you can move up in the world. you feed the plant and get more of what you want. this is central to capitalism, the whole crux of getting richer. if you want to be truly wealthy and successful, you're going to have to underpay and mistreat a lot of people: feeding them to the plant
and seymour wanted a better life, so much so that he was willing to hurt people. and honestly, a lot of people perpetuating these systems are people who think this is how they get a better life. they want to maintain the lifestyle they have, they can't stop feeding the plants
in the end, they plants take over and the world is eaten whole. it's like an apocalypse, and the way capitalism is destroying our ecosystem it's not hard to make connections to how our world could be if we keep indulging them
there's a line in this song: "if we fight it, we've still got a chance". this is a call to action, to me. no matter what, don't stop fighting for a better world. we still have a future, even if it seems bleak. if humanity can come together and refuse to drop another ounce of blood, we can survive
