I believe that the Constitution’s meaning is fixed, that whatever the words signified in the era of the Founders is what they still express today. If you don’t like the meaning, the Constitution provides a way to change it. It’s not easy to change and that is entirely proper. It should be changed only after due deliberation.
That said, court decisions over the years have changed the original meaning, sometimes dramatically. The commerce clause has probably been the most abused section of the Consitution. My opinion. So while a reading of the Consitution is easy and straight forward, knowing how federal case has defined and altered what you think it means it is a life's work.
A personal note. I was President of a national organization for some years. That Constitution provided the means to amend it, but only after the proposed changes were published to members three months in advance of a vote. This prevented the members from adopting knee-jerk proposals that were sometimes advanced at annual meetings. When these great ideas were put forward, I would remind them that we could take a straw vote right now, but that it would only indicate the support for the idea and that if the idea was to be adopted the Constitution’s prescribed means for changes would have to be followed. That always ended it as no one felt strongly enough about it to put it writing and proceed.
I recount this to show that while the means to change the Constitution are present, we are all a bit lazy to make the effort. We favor using the courts to chip away at changes.
On the other hand, knee-jerk changes protect all of us. Always remember that democracy led to condemning Socrates on a whim.
