White authors definitely shape what gets mainstream attention, but their influence isn't a single, clear stamp. It's more about the norms and traditions they've built up over time, which everyone else has to navigate. Think about how the 'Great American Novel' ideal often centers a certain kind of white, male, individualistic journey. That sets a bar, or maybe a default setting, that publishing tends to lean towards for what's considered 'serious' or 'universal.'
That said, it's less about all white authors writing the same way and more about the structural weight behind certain styles. Literary realism with dense psychological interiors, for instance, got a huge boost from a certain canon. Now, writers from all backgrounds are brilliantly subverting, expanding, or outright rejecting those forms. The influence is like a huge shadow you can either stand in, trace the edges of, or build your own light source to get away from. The most exciting stuff happening now often feels like a conversation with, or a reaction against, that inherited room.
