Question

Why might the delegates to the Constitutional Convention have made the Constitution so hard to change?

Answer 1

So some nobody can't just go up and change the laws, even till this day not any one can change a law or two. You must be in a higher position

Answer 2

So that the common, uninformed public could not make a "spur of the moment" descision that would radically alter the very foundation of our government. Also, so that a select group of people could not completely control the government. That's why the Constitution requires the majority of the people in order to alter it.
