Similar to how we investigate and figure out airplane crashes, the system should not allow you to get into those situations in the first place, that's the solution that works across time, instead of for just individual situations.

For example, how is someone who led/incited an insurrection against the government able to become head of said government? Already there, something is gravely wrong. You don't let undemocratic leaders lead a democratic society. So the system is broken, and the current administration is proof of that.

Otherwise what other commentators said will happen, someone who might even be worse than Trump will eventually lead the country.

So then again my question is who ultimately audits and holds the system accountable such that if the system needs to be fixed it gets fixed?

The only answer to that is the people who form the citizenry.

If the citizens cannot influence the system such that they can actually affect change on the system then they are irrelevant in it and the system needs to be replaced

As long as they continue to fail to organize then they will continue to be dominated by it

That’s just reality

There is no alternative organization that can counter the global capitalist system currently
