The necessary and proper clause in the United States Constitution grants Congress the power to create laws for the proper execution of its duties.
As such, all representatives from both the Senate and House of representatives who in turn represent the will of the people vote to pass laws in Congress to meet the expectations and needs of their communities. This, in turn, results in fewer amendments to the constitution since Congress can just pass laws to adapt to the needs of an ever-changing society instead of amending the Constitution everytime a movement of change is present.
