Children believe what they’re told. Doesn’t matter how unrealistic or uninformed the beliefs are, if you tell a child to believe trashcans are a portal to another dimension where trash monsters live, they’re very likely to trust you, because they haven’t yet had the life experience to think critically about their reality. Going further, they’ll hold onto things that are less easy to disprove to oneself. It’s very hard under capitalism to disprove indoctrinated ideals without the sources required to prove that another world isn’t only possible, but is logical.
