I think of something quite different from a snapshot. I know of a lot of poems, some very fine ones, that are like snapshots, but I'm more interested in poetry that is like an endless film, long stories, things that weave together many different strands, like a big piece of cloth, not like a photograph.
How much money you get, depends on lots of extraneous things. It depends on how good you are at turning poetry into a marketable product, which is something it was never supposed to be. That's why many people suppose that the better the poet you are the lower your income should be, and that's probably true.
