Financial system default crises can be rendered less frequent, and future bailouts of the financial system can be obviated, by private conversion of limited-liability corporate-form banks into non-corporate-form proportional-liability financial firms.
Such firms would be less prone to default than banks are, and would not need government insurance to protect their depositors – even if they keep the same employees, payrolls, physical plant and equipment, deposits, depositors, and outstanding loan portfolios as the banks from which they are converted.
