Unbalanced Vision

Just to show how pretentious UCL postgrads are, as having afternoon tea in kitchen can lead to a discussion on capitalism. This is how it all began when S asked if anyone wanted to join in the May Day anti-capitalism protest. So I guess it is my fault when I said, "So, what is capitalism? One word", while thinking what's the equivalent term in Chinese.
S: Why do you have to ask these exam questions?
R: No, just one word, what's capitalism anyways?
S: Exploitation.
E: No, it's not. It's about market and rights.
S: No no no... (she explains)
E: No no no... (he explains)
S: She wants one word. You said two words.
Maybe this white wall has the perfect answer?
