Consumerism, in Fight Club, is seen as an obsessive quality. What really seems to "matter" is money. The American mindset is not focused on what the rest of the world is concerned about-survival. Rather, it is concentrated on name-brand products and who has the biggest toys in the sandbox.
This points to an overall problem with the American cultural way of thinking. In general, Americans place too much emphasis on success by how much money one makes, what kind of car one drives, and so on and so forth. The fact is, Americans are driven by an inward-directed fear that they will not be financially successful and that is what drives Americans to be workaholics.
What the cartoon strip Calvin and Hobbes is really trying to chip away at is the fact that our values system as Americans is misplaced. While Calvin is a boy focused on playing and doing the things a boy likes to do, his friend and stuffed tiger Hobbes is just along for the ride-much like Tyler and Jack in Fight Club. Tyler, like Calvin in Calvin and Hobbes, is the sort of mastermind of the entity that is Tyler and Jack.
Like Calvin has
Like Calvin has Hobbes as his rapt audience, Tyler has Jack at his whimsy while they are hanging out. Tyler is ready to spout off his ideas about consumerism which consume him-usually with little or no protest coming from Jack. Tyler takes the stage, and is completely emotionally invested in becoming the star of the show.
Likewise, Calvin in the Calvin and Hobbes cartoon strip is a rather industrious sort of fellow, who takes over the show and has a consumeristic approach in his dealings with Hobbes. He is out to exploit Hobbes as a friend mainly because he can. Hobbes, since he is a stuffed tiger, is helpless at the whim of Calvin.
Similarly, this mirrors the philosophical bent and sheer brain power that Calvin the theologian and philosopher would have probably had over Hobbes the philosopher in real life were the twain to meet. For, Calvin has an excellent train of thought which would most likely outsmart Hobbes any day.
