Were I to distill “the dynamics of the current moment into a single image,” focusing on negatives, I’d seek out photos of children forcibly separated from their parents at the Mexican border; or addicts dead from opiate overdoses; or mass-shooting victims at a synagogue; or white supremacists beating counterprotesters in Charlottesville, Virginia; or lobbyists facilitating rent-seeking; or homeowners blocking the construction of apartments in their neighborhood; or segregated schools; or signs of climate change.
If you think the better choice is a photo of a smirking white 17-year-old, I suspect that the Donald Trump reelection team would thrill at letting you define the 2020 election. And I say that as someone who hates both the MAGA caps and the vicious campaign that popularized them.
