Why must consideration be sufficient but not adequate?

Consideration must be sufficient but not adequate because it serves as a legal mechanism to ensure that parties enter into a contract willingly and with intent. Sufficient consideration means that the value exchanged is recognized by the law, ensuring a basic level of exchange. However, it does not require that the value be equal or fair (adequate), allowing parties the freedom to negotiate terms based on their individual circumstances and preferences. This flexibility fosters a diverse range of contractual agreements while maintaining legal enforceability.
