Nobody wants to admit that the Constitution is broken

The Constitution was designed to prevent majoritarianism--the tyranny of the majority. Perhaps this was a response to the years of arbitrary rule from the other side of the Atlantic, fresh in the memories of all the Founders.

The problem is that the Constitution succeeded so well at this that it left America vulnerable to minoritarianism--the tyranny of the minority.

This is why subsequent democracies adopted a parliamentary system instead of ours. That system isn't perfect--none is or ever will be--but it does enable government to function, while also enabling the majority's decisions to be challenged electorally whenever the tide goes against those in power.

Whereas our system enables a small minority to sabotage government and, in the case of America, even the world economy. No one is ever responsible for anything, because each can always point the finger at the other and say "If not for their interference Paradise would have been ours."

That's one of the worst consequences of our system: the dilution of responsibility for what the government does or doesn't do.

One thing would go a long way to fix this, short of a Constitution Convention leading to the adoption of a parliamentary system (the system that works efficiently for most of our fellow rich nations): a Constitutional amendment mandating nonpartisan redistricting nationwide.

That isn't a cure-all but it would reduce today's invulnerable  incumbency in most Congressional seats--and it would eliminate the ability of Republicans in some states to control the state legislature despite being in the minority in some states they control.
