Where does that accountability lie? Is it the politicians, the voters, the banks, human nature. The fault lies deep and I believe it's in all of us, in our desire to consume more than we produce, to write checks on mothers wombs.
I would say the responsibility lies mainly in the politicians. Supposedly we vote them into office to be responsible representatives of our interests. If now we're paying for the mistakes some of them did while in government I think there should be some accountability to be had. That would be the expectation in any other job that I know of. Ok, maybe except banking.
Some Italian city-states used demarchy (policy juries); the Quakers and kibbutzim used parpolity or sociocracy (cellular democracy); and many pre-historical societies used kritarchy (policy judges). There are, of course, many other options, but I thought these were some of the more interesting ones.Democracy seems at least somewhat broken but what else do we have?
