Does Homo-Economus Really Exist?

Interpret this T-shirt please.

Recently I saw a person wearing a shirt which read, “Does Homo-Economus Really Exist?”

What does this mean?

My WAG would be that it’s an in-joke for economists. I guess even economists have a sense of humor (not much, though). Here is one of many Google hits for “homo economus”.

[shrug] You tell me. Is it funny?

I hope it’s meant humorously, because it sounds like a modern version of communist/socialist retoric- that to get Communism to work, you must eliminate “capitalist” thought patterns.

Wouldn’t homo-economus be the mythical man who makes rational decisions who underlies traditional economic theories?

So you would be homo-malapropist?

yeah, I know that sucked
