I think we’re in agreement. Even if we steelman their argument, it doesn’t follow that the workers ever see the benefit of reinvestment. The capitalist is still incentivized to reduce the cost of human labor through various means (understaffing, wage theft, offshoring, AI, etc.). Much more equitable for the workers to collectively make decisions about production instead of capitalists.

Yes, the meme simplifies their position for the sake of humor. But Trickle Down Economics is demonstrably false and worthy of ridicule.
