I would like to begin by recapping the role of the public sector. Markets have their uses, but they are not to be confused with democratic institutions. Markets might be useful in determining the price of goods, but they should never be used as mechanisms for determining our values as a community.
Markets are oblivious to morals.
They were never designed to be moral instruments. A market can and has existed in anything. To take an example from our own history, a slave market thrived on this continent for over 300 years. And this market did not collapse on its own. Markets are no substitute for the democratic process.
