> socities that do not have well-developed financial markets to directly see and appreciate the value financial markets
Which is true, but there's another angle that needs discussing - that of a high-trust society vs low-trust society.
In all places where there are well functioning financial markets, there exists a high trust society. This trust is the foundation on which the financial markets exist.
So in poorer countries where such financial markets don't exist (or don't serve the people), it's not because they've chose not to have it, but that individual actors cannot trust that the system is fair and is rules based. So the problem isn't the lack of financial markets (which is a symptom), but that of a lack of good governance (bad or non-existant laws, corruption etc).
