There are more important things to consider now. Debating this is not a good use of time because without addressing immediate threats to national security it would be for nothing.
Their design prevented power from accumulating in DC? Really? Do you believe that is how things are now? That power is not concentrated in DC? Please tell me how you justify such a premise that their design is fulfilled and operating now? I must ask, are you blind or simply filled with innocent idealism?
They believed, wrongly, that people would understand that without personal negative consequence the there is no responsibility. They provided the means to destroy in the amendment process and that was fulfilled when the vote was given to people who do not have a stake in negative consequences. Those are the people that God always makes more of, the have nots and then people without honor have caught on that they can vote themselves a raise from the treasury with the money of the productive portion of the population.
Am I my brother’s keeper? Is that my responsibility? The founders thought people would have better sense than to allow what has happened.
Yes. Prior to 1913 the federal government wasn't a factor in the life of the average American.
Do you believe that is how things are now?
No. Overnight, the 17th Amendment rendered the Framers' federal republic into a democratic republic. Whereas power was previously diffused between the states and government they created, the 17th immediately concentrated power in DC.
The Constitution acts upon both the states and the people. Both were represented until 1913. It makes as much sense to remove the states from the government as it does to remove the people . . . none.
James Madison summed it up nicely in the fourth paragraph of Federalist 51
