The previous article in this series critiqued the Obama administration's proposal for a new federal reinsurance program on the grounds that it did not address the three major structural defects in the current housing finance system: the excessive market power of four mega-banks, the barriers to effective shopping by mortgage borrowers, and the vulnerability of the private secondary market to a contagious loss of confidence.
