I agree, the tide analogy kinda breaks down here though. We're all familiar that it's somewhat rare that a technological advancement goes from no usage to film and wide distribution in one step. New technologies are distributed only to the rich precisely because they are time and resource intensive to develop and can only be feasibly prepared via a process which will inevitably occur costs that the majority of humans will not be able to meet. But you _need_ those first few rich people, because the money they put in starts the feedback cycle that would not be able to start otherwise. Ideally this then begins a process of optimization which gradually allows these products to become available to everyone.

Inequality is the price of innovation, but it doesn't have to be paid forever.
