You think the government cared about lead paint? Or clean water? They wouldn't have allowed it to be sold if they did. Only when it was a threat to citizens and then linked to paint and gasoline that had been sold for decades, making it a possible crisis in public health and public discussion but also importantly to huge libel lawsuits for corporations.
You think the government thinks? Or do you think the people who are elected into office are the ones that do that?
Also the government (generally) doesn't tell people what to sell. That is not how it works, people think of something that they think they can make money on and produce it, people who want it buy it, use it, and after a while, if enough is pushed out into the world that people who did not benefit from it have to deal with it.
That is usually the point that Government comes into play if it turns out to be toxic or whatnot. At that point those people who are in government at the time have to make decisions on what to do. Unfortunately for way too long those decisions were only being made by about 30% of our population and information was not nearly as good as it is now. So it took a lot longer to figure out the mess they were making. Especially since the wealthy white people could just move away from their ecological disaster to a fresh shiny new suburb leaving minority and poor communities to sit in their messes.
That is why the posts I made that you basically just ignored matter so much. By having the other 60% of the population represented, people can and are making far better decisions because they have a much more complete picture of what life is like all across our country. Unfortunately that is only occurring in one party at the moment.
And anytime they get in power, shit like what you are posting crops up and tries to convince people that voting doesn't matter so the status quo keeps their upper hand.
