Last year a researcher at I believe Illinois discovered that when white students are exposed to evidence of systemic racism, their memories of their own poverty become more intense even to the point of (to put it politely) “confabulation”. White people, when shown they have an advantage, actually invent disadvantages we had to overcome, and come to believe them.
After I learned this, I took on two behavior changes: I don’t talk about the material conditions of my childhood anymore, and I don’t include class when I look in intersectional questions. And after a few months of this, I think it’s the right thing to do.
Whatever poverty did to me as a child, it didn’t limit me or define me. White poverty (even when intergenerational) is capable of being and is seen as being transient.
