The law of unintended consequences continues to apply to laws made by Congress.  The Associated Press conducted an investigation on the content of Chinese children’s jewelry products and found that a 12 out of 103 sample jewelry items contained over 10 percent cadmium.  Cadmium (not regulated by U.S. law) is more dangerous than lead, which is regulated by a federal law called the “Consumer Product Safety Improvement Act.”  To avoid the high cost of testing for lead in children’s products, some Chinese manufacturers of products intended for children are now using a much more dangerous substance instead of lead.
