The elimination principle discussed in this chapter tells us what we can expect in the long run from perfectly competitive markets: zero (normal) profits across industries. If this were the case, and this fate were unavoidable, going into business would seem to be a fairly dismal choice, given that the end result of normal profits is known right out of the gate. Despite this, we constantly see entrepreneurs working hard to earn profits. Is this a waste of time, given what we know about the elimination principle? Is the fate of zero profit unavoidable?
