USA is rapidly deindustrializing and there is no
necessity in damn science kits for kids. Kids must
know what is credit card, lawyer, insurance and mortgage.

Americans. Do not invent new measures. Look what Europe (or even Australia and UK) does and just follow the wise.
Instead of excessive tests for science kits it better if you ban unsafe components (such as azodicarbonamide and trans fats) from bread, ban corn syrup, stop importing apple juice from China, or some other, REAL things.
