I'm not sure who the "we" in your message refers to, but I've read this work and I think it's a very accessible, quick comment on the disastrous effects that a resistance to change can have on an organization.
The mouse-cheese analogy, though somewhat hokey and tiring, works to illustrate how to many individuals, managers, CEO's, whomever become too satisfied with the status quo of their pcoketbook or company and fail to think forward. Obviously, in the one mouse couple's case, they thoughttheir resources superabundant and were vexed when they realized that they would actually have to move, change their perspective, and do addtional work to replenish their resources and stay afloat.
So, all in all, a good message about flexibility and strategic thinking.
