One way—maybe the best way—to grow political power is for the politicos to promise to "fix" or "reform" something. Within this category is the notion of piling on regulations to virtually eliminate risk from our lives.
The only problem here is that there is lots of risk in trying to do this!
Banning DDT killed millions of Africans, with absolutely no measurable benefit to the environment is one example. Recently, the geniuses promoted ethanol as the wonder fuel caused both food and fuel prices to skyrocket. As a matter of fact, we were all over that one.
And of course, not allowing a refinery to be built since 1976, and severely restricting drilling didn't help, either.
In my recent Health News Digest piece, I cite a few more examples of the so-called "unintended consequences" of bad policies, and how a horrible Supreme Court decision protects the Feds even if they totally screw up and it's all their fault. Check it out.
