Behold the tyranny of Equestria’s unfettered capitalism!
One of course realizes now what the cutie marks actually mean: a representation of the division of labor and the division of Equestria into classes. Here we see 3 noble fillies, each of them “blank” meaning they are unburdened by the pressures of proletariatism. In true, glorious communist fashion, they are not subordinated to a single talent, bound to it or exploited by it. They know everything as a whole! They are well-rounded and multi-talented. (They even let Apple Bloom attempt a psychic test, even though magic is exclusively the domain of the unicorns.)
It is a shame they do not realize their true use and utility as well-rounded ponies, their faculties developing in balanced fashion. They could truly revolutionize Equestria and help it reach communist utopia! But alas, they have soaked in too deep the bourgeoisie propaganda and so do not realize their potential.
Truly, the most tragic and sad episode of the season.
(Or maybe it’s all about how sometimes we can screw up our own efforts, such as finding our special talent. When a talent show comes along.)
