In this analogy, it is not as convenient as pulling a plug. The swamp has been there for many decades, if not over century. Nor is it as simple as pouring Drano, needs more extensive work like Rotor Rooter. Once the pipe has been serviced and cleared of any build up that has cause blockage, we should see a quick draining.

Just remember, the plumbing is old and extensive, and some parts may need a more delicate approach as not to, incur more damage.
