One of the intractable problems is that the people who could benefit most from financial inclusion in principle are also the ones least likely to have a financial education.
Who is hurt most by lack of access to financial system? The poor.
Who is most likely to lack financial education? The poor.
This is one of the main arguments for gatekeeping on risky investments, but low risk investments lack the risk premium. In general I oppose paternalistic policies that are designed to protect a particular segment of society from themselves. We should come down harder on fraudsters, not exclude people from the financial system.
