In short, if Contract is viewed as a system of dealing with consensual obligations, then the premise of a bargain is both necessary and desirable. The difficulty is that under the current state of the law, operative facts sufficient to establish the existence of the requisite "bargain" often fall far short of guaranteeing the existence of real assent to the exchange. It is in this gap that the adhesive form contract, because it often removes the knowledge and choice essential to real assent, thrives best.
