My suggestion is to take John Kenneth Galbraith's The Good Society: The Humane Agenda and Economics and the Public Purpose and update them in light of MMT. Of course, these books segue into lots of other relevant contributions No need to reinvent the wheel, just return the conversation from the trivial to the important. However, I think that "the good society" and "public purpose" are a good lede.
As Alex notes this is essentially a philosophical issue. As I have said, it goes back to ancient Greece in the Western intellectual tradition. The Greeks were absorbed in the question of what it means to live a good life as an individual in a good society. Aristotle observed that humans are social animals and therefore the good life must include citizenship.
The Greeks also introduced liberalism as the prioritizing of freedom. Freedom from constraint and freedom to choose are necessary for freedom for self-actualization as an individual and self-determination as a state (Gk: polis).
In my experience, ethics and aesthetics rest on ontology and epistemology as a foundation, and social and political philosophy rests on ethics. For example, one's world view ("philosophy" in the broadest sense) is foundational since one's world view is the conceptual model of reality that one employs.
A key fundamental in a world view is the conception of human nature, for example. One's conception of human nature greatly influences one's world view both individually and socially. See, for instance, Twelve Theories of Human Nature, which is hardly exhaustive.
Here is a comment I left at The Multidisciplinarian yesterday that speaks to this:
I also came to the conclusion over the years that it's not possible to deal with social and political philosophy without also dealing with both the philosophical foundations of economics and political economy. Since economics now concerns monetary production economies that also involves money & banking, and finance.
This is a big chunk and no one person is going to resolve the issues. But some people need to get the ball rolling if this debate is to take place.
The world badly needs an undated theory of liberalism made practical as an antidote to the faux liberalism that is actually illiberal, or, in the criticism of Karl Marx, bourgeois liberalism grounded in the freedom for accumulators to accumulate based institutional power and the power of the captured state.
