It is unlikely that consumers will ever hold much influence over the realities of the financial regulatory process because they are not organized in comparison to the financial industry, which concentrates significant resources in the creation of inefficient regulators. By and large, consumers are not well-informed about what they have at stake in the regulatory process and, even if they were, that would not be the sole determinant of how they define themselves politically.
Adding another layer of guards to guard the existing guards ultimately results in an infinite regress. I do not think it is cynical to suggest that, absent an actual paradigm shift with respect to accountability in the financial industry, we are just going to have more of the rent-seeking that has gone on to date and the economic calamities that ensue. For my part, I would propose opening up financial regulation to a small group of social entrepreneurs. Let people establish for-profit companies that can compete for government contracts to stress test the holdings of financial institutions independently and audit their records.
