How government makes things worse
WHAT DO ethanol and the subprime mortgage meltdown have in common? Each is a good reminder of that most powerful of unwritten decrees, the Law of Unintended Consequences - and of the all-too-frequent tendency of solutions imposed by the state to exacerbate the harms they were meant to solve....

...But now comes word that expanding ethanol use is likely to mean not less CO2 in the atmosphere, but more. Instead of reducing greenhouse gas emissions from gasoline by 20 percent - the estimate Congress relied on in requiring the huge increase in production - ethanol use will cause such emissions to nearly double over the next 30 years.

The problem, laid out in two new studies in the journal Science, is that it takes a lot of land to grow biofuel feedstocks such as corn, and as forests or grasslands are cleared for crops, large amounts of CO2 are released....

...The subprime mortgage collapse is another tale of unintended consequences.

The crisis has its roots in the Community Reinvestment Act of 1977, a Carter-era law that purported to prevent "redlining" - denying mortgages to black borrowers - by pressuring banks to make home loans in "low- and moderate-income neighborhoods." Under the act, banks were to be graded on their attentiveness to the "credit needs" of "predominantly minority neighborhoods." The higher a bank's rating, the more likely that regulators would say yes when the bank sought to open a new branch or undertake a merger or acquisition.

But to earn high ratings, banks were forced to make increasingly risky loans to borrowers who wouldn't qualify for a mortgage under normal standards of creditworthiness. The Community Reinvestment Act, made even more stringent during the Clinton administration, trapped lenders in a Catch-22.

"If they comply," wrote Loyola College economist Thomas DiLorenzo, "they know they will have to suffer from more loan defaults. If they don't comply, they face financial penalties . . . which can cost a large corporation like Bank of America billions of dollars."

Banks nationwide thus ended up making more and more subprime loans and agreeing to dangerously lax underwriting standards - no down payment, no verification of income, interest-only payment plans, weak credit history. If they tried to compensate for the higher risks they were taking by charging higher interest rates, they were accused of unfairly steering borrowers into "predatory" loans they couldn't afford.

Trapped in a no-win situation entirely of the government's making, lenders could only hope that home prices would continue to rise, staving off the inevitable collapse. But once the housing bubble burst, there was no escape....
