I agree with this image, and I'm quite curious to see what "rich" tastes like... But I feel like the mechanics of this picture took me a second or two longer than it should to understand.
Edit: like are they balancing their unicycles on the larger cylinder? They must have really good balance to manage that for more than a second. And if that is true, what happens if they fall forwards? I see the danger if them falling backwards, but does that mean they just can't fall forwards?
For Capitalism there should be multiple different money scoops, some better designed than others. There should also be a greased-up rope that leads from the unicycle-bar to the top, showing that it's theoretically possible to rise to a different class, it's just practically impossible.
