Yes, i think there is a panel where it tells you that some worker for a 3 room apartment pays 10% of their salary. Then they show you a standard 3 room apartment and while going through it I was so surprised because I would never be able to afford anything even close to it.
But all the museum is about how people where oppressed and poor !?

You know what, I feel like the shell part of the turtle is best represented by the "turt" part of the world turtle. It just looks the way "turt" sounds.
So a turtle without it's shell I think should start to be called a "le" (pronounced like in the world turtle), which represents very well, as a sound, a "turt"-less turtle
