Ever heard of the tale of the goose that laid golden eggs?
Imagine progressively feeding the goose less, so as to have a greater profit margin on the golden eggs it laid. No particular percentage of feed reduction seemed too harmful, until one day it died unexpectedly.
Just to be clear on the analogy, the goose is the tenants, and the person feeding it less every day is the landlord class?
This sounds like private equity, except they'd also demand that the goose increase egg production by 10% per quarter.
