I wanted to say something about the fact that people don't seem to be concerned about their children's safety as long as they can save money.
General observation:
People don't consern themselves with anything that does not benefit them. If something makes things more convenient, saves or makes money there is nothing wrong with it. Cant be. Nope. Nya nyanyanya ...
People, when one on one, are pretty cool. There are very few people who can't understand simple concepts. However when in heard they aren't that bright.
I went looking for lead testing kits, short search, the ones I found are aimed at the home owner, not someone doing multiple samples and assays. It would be labor intensive but probably not that expensive.
Of course there is a simple sollution. Sell no lead replacements, thread and needles at the front register. I know, it's awful of me to expect someone to learn some 8'th grade home Ec.
Next thing you know I'll want these people to quit poisoning their charges with industrial food.
What gets me is, HOW DID LEAD GET INTO THIS COUNTRY IN THE FIRST PLACE? I've go to garage sales and auctions looking for the ever elusive lead pipe dope, and powdered lead for machine building .... It's a fanticy. Mentioning this stuff in a store gets you looked at funy.
I would like to say we've been too lax with regulation with items made in china. We chould make a tarrif on stuff from China to help pay for inspection, monitoring and the replacement of the buttons.
OTOH we in the west have been sending our toxic garbage to China for at least a decade, they use their children to scrap out the 'garbage' and all sorts of nastiness is in their air , food and water. And the Chinese children ingest it.
