In order to reform regulations we need first to reform the regulators.
First we need a totally new crop of regulators, most especially in the headquarters of the Basel Committee as those currently there have dug themselves so deep in their framework they have no earthly chance of getting out of it. As an example they cannot even visualize a world without “trustworthy” credit rating agencies when we all know well that no one but God should be given so much trust.
Second there must be some type of accountability. For instance the thousands of licensed professionals involved in generating those masses of lousy mortgages to the subprime sector should, as a bare minimum, have their license revoked for five years.
