When I am not teaching kids cooking classes, I often work at the store next door, which sells toys. I do a lot of deep thinking when I am pricing or displaying products.
For example, why do girls play with beautiful dolls (ie Barbie), pretend purses, and mirrors? Why do boys play with trucks and trains?
Have Barbies given girls low self esteem and body image issues? Not many girls can compete with the plastic form of a Barbie doll.
And why is pink a feminine color? (A quick history on gender specific colors here.)
The extent to which gender is/has been exaggerated according to popular societal values is almost impossible to measure.
