Here is a link to an interesting four-part lecture series by Mary Mellor, filmed in February 2012 (h/t Tom Hickey at Mike Norman Economics):
The first part traces the historical development of money, emphasizing its social nature. The middle two parts concern money and banking, and the crisis. The fourth part, which most motivated me to link to the lectures, considers the social potential for democratized money to enable sufficiency, sustainability, and social justice.
The social potential of democratized money has been a preoccupation here at heteconomist (see, for example, Money and Paths to a Post-Capitalist Society). The viability, under such a system, of economic activity not driven by profit or reliant on growth is discussed in MMT is NOT a Theory of State Capitalism (!).
I was interested to note that as part of a broader democratic determination of economic priorities, Mellor regards a citizens' income and right to meaningful work as requirements for social justice. This would broadly resemble a participation income or, perhaps, a Job Or Income Guarantee.
