Homo Economicus

Saturday Morning Breakfast Cereal
I can't make the picture any bigger, so please click on the link to read the cartoon at the site.

What is the assumption in this picture?

Why is this man's actions not okay?

The cartoonist portrays 'normal human courtesy' as the Homo Sapiens.
Do you think the first picture is really about normal human courtesy?
Isn't there also an economic assumption implicit in that scenario?

Why is this woman's statement not okay?

What about this statement is an economic decision?

What is the difference between these mens' statements?

What do you suppose is the point the cartoonst is trying to make?
Do you agree with his points?
