COMPU-TEACH: Good morning life-form. 
PUPIL: Hi teach. 
COMPU-TEACH: Are you sitting comfortably? 
PUPIL: Yes. 
COMPU-TEACH: Then stand up! Harsh Economic Truths, Class Seventeen. You are standing up? 
PUPIL: Yes. 
COMPU-TEACH: Good. Posit: you are living in an exciting, go-ahead civilisation. Where are you looking? 
PUPIL: Up. 
COMPU-TEACH: What do you see? 
PUPIL: The open sky. The stars. An infinite horizon. 
COMPU-TEACH: Correct! You may press the button. 
PUPIL: Thank you. 
[Button is pressed. A surge of energy] 
PUPIL: Wow! That feels nice. 
COMPU-TEACH: Posit: you are living in a stagnant, declining civilisation. Where are you looking? 
PUPIL: Down. 
COMPU-TEACH: What do you see? 
PUPIL: My shoes. 
COMPU-TEACH: Correct! What do you do to cheer yourself up? 
PUPIL: Uhm… press the button? 
COMPU-TEACH: Incorrect! Think again. Your world is a depressing place; you are looking at your shoes. How do you cheer yourself up? 
PUPIL: I buy a new pair. 
COMPU-TEACH: Correct! 
PUPIL: Can I press the button? 
COMPU-TEACH: All right. 
[Button is pressed. A surge of energy] 
PUPIL: Wa-ho! So nice. 
COMPU-TEACH: Now, imagine everyone does the same thing. What happens? 
PUPIL: Everyone feels nice? 
COMPU-TEACH: Ah, forget the button! Concentrate! Everyone buys new shoes. What happens? 
PUPIL: More shoes. 
COMPU-TEACH: And? 
PUPIL: More shoe shops. 
COMPU-TEACH: Correct. 
PUPIL: Can I - ? 
COMPU-TEACH: No, no. 
PUPIL: Oh-oooo. 
COMPU-TEACH: And in order to support all these extra shoe shops, what must happen? 
PUPIL: Everyone… must keep buying shoes. 
COMPU-TEACH: And how is that arranged? 
PUPIL: Manufacturers dictate more and more different fashions and make shoes so badly that they either hurt the feet or fall apart. 
COMPU-TEACH: So that? 
PUPIL: Everyone has to buy more shoes. 
COMPU-TEACH: Until? 
PUPIL: Until… everyone gets fed up with lousy, rotten shoes. 
COMPU-TEACH: And then what? 
PUPIL: Why can’t I press the button? 
COMPU-TEACH: And then what?! Come on! 
PUPIL: Massive capital investment by the manufacturers to try and make people buy the shoes. 
COMPU-TEACH: Which means? 
PUPIL: More shoe shops. 
COMPU-TEACH: And then we reach what point? 
PUPIL: The point where I press the button again. 
COMPU-TEACH: Oh, all right. 
[Button is pressed. A surge of energy] 
PUPIL: Wa-hoo! Ahhhh… So nice, that’s really nice! 
COMPU-TEACH: And then we reach what point?! 
PUPIL: The Shoe Event Horizon! The whole economy overbalances; shoe shops outnumber every kind of shop! It becomes economically impossible to build anything other than shoe shops, and bingo, I get to press the button again! 
[Button is pressed. Another surge of energy] 
PUPIL: Wooo! 
COMPU-TEACH: Wait for permission! Now, what’s the final stage? 
PUPIL: Umm. Every shop in the world ends up as a shoe shop. 
COMPU-TEACH: Full of? 
PUPIL: Shoes that no one can wear. 
COMPU-TEACH: Result. 
PUPIL: Famine, collapse, and ruin. Any survivors eventually evolve into… birds and never put their feet on the ground again. 
COMPU-TEACH: Excellent! End of Lesson. You may press the button. 
[Button is pressed. A surge of energy] 
PUPIL: Woo-ha-ha! Yee-he-hehooo! Ah-ha. Oh, that’s nice. Thank you teach. Goodbye. 
COMPU-TEACH: Ah-ah! Aren’t you forgetting something? 
PUPIL: What? 
COMPU-TEACH: Press the other button. 
PUPIL: Oh, right. 
[Other button is pressed. A big surge of energy] 
COMPU-TEACH: Oh-ho-ho! Ooooo, ooooo-waaahhh! Oooo-hooo-weee-ha-hah!!
