Why public subscription campaigns for warships faded

Why do public subscription campaigns no longer raise money for ships as they once did?

Because Navy League-style political advocacy faded after the Second World War, when leaders assumed the public would permanently remember why a navy was necessary.

Public subscription campaigns faded with the political culture that had sustained them. The Navy League once promoted naval causes and translated sea power into public argument. After the Second World War, leaders assumed the need for a navy was self-evident and allowed that machinery to disappear. Public memory is perishable, so institutions must keep explaining naval requirements after a war appears to have settled the case.
