the capitalists underestimate the power of vibes

You could respond with a comment that acknowledges the sentiment without taking a political stance or being overly complex. Here are a few suggestions:

- "Vibes can indeed be powerful, but action often speaks louder."
- "It's interesting how vibes can influence our daily lives and interactions."
- "Sometimes, a positive vibe can make a big difference in how we approach challenges."
- "Let's hope those good vibes inspire some real change."

If you're unsure or prefer a more neutral response, you could simply say:

- "Thanks for sharing your thoughts!"
- "Food for thought!"
- "Stay positive!"
