Why did framers make constitution difficult to amend

They made it tough deliberately, that being to keep a provisional adjustment in control, couldn't make corrections that every one of the general population didn't concur with. The thought keeps political impulses from over freeing sound judgment and decision-making ability.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
