Nearly 16 years ago in these very pages, I wrote that "'one-size-fits all' rules for business ignore the reality of the market place." Today I'm watching some broad rules evolve on individual decisions that are even worse.

Under the guise of protecting us from ourselves, the right and the left are becoming ever more aggressive in regulating behavior. Much paternalist scrutiny has recently centered on personal economics, including calls to regulate subprime mortgages.

With liberalized credit rules, many people with limited income could access a mortgage and choose, for the first time, if they wanted to own a home. And most of those who chose to do so are hanging on to their mortgages. According to the national delinquency survey released yesterday, the vast majority of subprime, adjustable-rate mortgages are in good condition,their holders neither delinquent nor in default.

There's no question, however, that delinquency and default rates are far too high. But some of this is due to bad investment decisions by real-estate speculators. These losses are not unlike the risks taken every day in the stock market.

The real question for policy makers is how to protect those worthy borrowers who are struggling, without throwing out a system that works fine for the majority of its users (all of whom have freely chosen to use it). If the tub is more baby than bathwater, we should think twice about dumping everything out.
