Meet Roberta Karmel, an unassuming law professor. Meet Professor Karmel's answer to finally break up the big banks.

Another financial crisis, a prolonged recession, or changing political ideologies could cause a re-examination of the status quo and lead to a decision to break up the big banks. If that should happen, policy makers could well take another look at the Public Utility Holding Company Act of 1935 as a model for accomplishing such a breakup over a limited time span of, say, seven years. The political mood is already shifting. The 1980s mantras -- government regulation as problematic, free-market competition as an unquestioned good, financial engineering as worthwhile innovation and finance as more important than commercial and industrial enterprise -- are now being reconsidered. This could lead to a more responsible balance between government, finance and industry. Dodd-Frank, despite its length and complexity, is only the beginning of real regulatory reform. It's a continuation of the complexity of already overly complex financial and regulatory systems. What we need is a simple regulatory scheme to create a simpler banking system.
