For children with parents, relatives, and/or others who may be role models for pursuing a passion outside of gender stereotypical roles, the affirmation from other sources may not be key.
However, to broaden the encouragement of ALL children who may have an interest in science, technology, engineering, and/or math, a layering of social messages which affirm girls' interest beyond gender stereotypical roles is a refreshing and welcome support. Positive t-shirt messages are just one way to affirm, support, and encourage the growth of girls' interest in STEM throughout their developmental years.
With affirmation, some of these children may become the FIRST in their family to become a doctor, etc. This is not a caste society; Upward social mobility is part of the American Dream.
