The B3 AFs symbolize ?

The B3 AFs symbolize the problematic nature of social stratification. The B3 AFs are newer, supposedly more advanced models of AF. As Klara observes, the B3s view older AFs with disdain, apparently believing them to be inferior. The B3s function in part as narrative parallels to the views of ‘lifted’ children versus ‘non-lifted’ children.
