I don't follow domestic regulation as closely as many people at Cato, but I keep an eye on it in relation to "regulatory trade barriers" that are being addressed in trade negotiations. In that context, I came accross this EU attempt to crack down on high-wattage vacuum cleaners:
Consumers are being urged to buy powerful vacuum cleaners while they can after it emerged that some of the most powerful models on the market will disappear in September when a new EU rule comes into force.
An EU energy label, to be introduced from 1 September, means manufacturers will not be able to make or import vacuum cleaners with a motor that exceeds 1,600 watts.
European commission spokeswoman for energy Marlene Holzner said in a blog: "As a result of the new EU eco-design and labelling regulations, consumers will also get better vacuum cleaners. In the past, there was no legislation on vacuum cleaners and companies could sell poorly performing vacuum cleaners."
Oh, the humanity! Companies might sell "poorly performing vacuum cleaners" to an unsuspecting public! And only legislation can save the day!
Or -- and I know this might sound crazy to some people -- we could just rely on consumers to evaluate the vacuum cleaners, buying the better ones and leaving the "poorly peforming" ones on the shelf.
