Based on the lack of participation in this forum I'd say the country has failed the constitution.
None the less, here's an interesting take.
Given the massive welfare-warfare state system under which Americans live, the natural assumption is that the Constitution failed in its mission to constrain the powers of the federal government.
Actually, though, that isn’t the case.
That seems like an odd theory to start off with, given that you are implying that the law has the duty to constrain the public.... isn't it the public's duty to be constrained by the law?
Let me put it another way:
We have laws against murder. Yet we have people who commit murder routinely.
Did the law fail? Do we need to toss out the law, and replace it with a new law? It's not stopping murder by having it illegal, so the law must have failed?
Or maybe we the public have failed to fully enforce the law?
Maybe the public has failed to enforce the constitution on the government?
This is my complaint against all the people who say we need a constitutional convention, and a new guiding document.
The problem with the constitution, is not that it doesn't work. The problem with the constitution is that we are simply not following it.
And if the problem is that we are refusing to follow the constitution..... then what difference does it make if we replace it?
If we replace the constitution, how is having a different constitution going to make anything better? Won't we not follow that either?
This is a bit like the gun control debate. The last mass shooter we had, the guy shooting had violated over 11 different gun control laws. When he didn't follow the first law, why did you think having another law was going to make a difference?
We added a dozen laws, and what a shock, he didn't follow any of those laws either.
So let's create a new constitution, and then we won't follow it anymore than we're following the current one.
No, the solution is to get back to following the current constitution. The basic principals the founding fathers built into the constitution, created a nation that became the economic, and military leader of the entire world, among nations that had existed for thousands of years longer.
It works, we just need to get back to following it.
