Here's an example of how California arguably over-regulates. California Proposition 65 requires businesses to post a sign warning customers about the potential presence of significant amounts of toxic chemicals in their locations. That sounds like a good idea!
But the devil is in the details. During our winter break trip to southern California, the place we were staying at had one of those Prop 65 signs posted in its underground garage. Yikes! Toxic chemicals in the garage? What we were exposing ourselves -- especially our boys -- to?
The sign didn't say, which made it all the more ominous.
By scouring the information binder in our room, however, I was able to determine that the toxic chemicals in question were . . . secondhand cigarette smoke and automobile exhaust.
No doubt Prop 65 is well-meaning, but if it requires businesses to warn about secondhand smoke and automobile exhaust, it risks becoming worthless through over-warning. It's much like highlighting every line in your textbook -- there's no differentiation.
