...Have you heard about the amendment process?
Yep.
In the case of "interpretation" is it NOT the WORDS that change.
It is the MEANING of the words.
A word (or collection of words) can be spun in multiple directions.
Spin A works for a while.
Then somebody comes along and says, well, what that really means (or can be construed to mean) is B.
If the needs of the People and the Republic evolve to embrace B rather than A, then the Supreme Court rules on whether that's legitimate, in a Constitutional framework.
If they find in favor of Spin B, then B controls, from that point forward.
Checks and balances.
Evolution.
Living, breathing Law, metaphorically speaking.
It's the way the world works.
It's the way the Founding Fathers
intended our part of the world to work.
Sometimes it works in favor of Liberals.
Sometimes it works in favor of Conservatives.
But it works; it's one of the three pillars of the governance of the United States.
If you don't like it, you can always move to Russia, where their checks-and-balances may prove more to your taste.
