To make sense out of why you said the above at this point in the conversation, I have to assume you anticipate that most proposed amendments would help the poor. There is no reason at all that such would be the case. Amendments that hurt the poor would be much more likely. The majority of Americans aren't poor, and legislating is a majoritarian exercise.

Many people wish the Constitution was more malleable because then their idealistic wish list could be enacted. Yet it's much more likely that the wish lists of the most cynical manipulators of majority opinion would be enacted.

Donald Trump was elected once and was almost elected again. What sort of amendments do you think Donald Trump would propose if amending the Constitution was easier? How willingly would his cultlike following support his propositions? How hard would it be for him to swing some independents his way if he played upon their baser instincts?
