I blame human nature more than specific deficiencies in the Constitution...although I’ve often wondered how we’d have done if we’d have never ditched the Articles of Confederation.
As Adams (our first liberal president) pointed out, our form of government requires a moral populace. Our largely successful republic produced such a long period of freedom and peace that we started to take it for granted. Our culture has deteriorated to the point that we now have as many people happily on the dole as those providing the funds. Under these conditions, given time, humans will do whatever is necessary to change the meaning of the constitution to remove the limitations it imposed on the federal government. Any unconstitutional law that slips through becomes precedent for the next via “stare decisis”.
We are in the midst of a marxist takeover, yet even the victors are unaware of that fact. The final stage will progress very rapidly...and is just around the corner. Keep your powder dry.
I suspect the powder of which you speak is very dry among Freepers. :)
