The capitalist project has failed, and our Constitution - poorly written even for the time - is wholly unequipped to deal with the crisis, nor the emergence of highly ideological political parties.
I agree overall on both points, but it's worth noting that the founders intended for the constitution to be amended much more frequently than it has been.
The challenge becomes what to do next. Do we follow Lenin's teaching and attempt a revolution, do we structure our society around trade-unionism, do we need to invent a new form of government, or are we destined to a fascist future ruled by increasingly imperial powers?
