If there is a legitimate public interest then the government should create an inspection scheme
The problem is that the public doesn't always know any better or know what is going on without the undercover folks investigating and making a big deal about it. It would be different if we could trust policy makers to investigate some of the stuff or listen to the science, but at this point (at least in the US), that's not happening.
>That's the government's job, not private activists Sure, maybe it is the government's job technically. Unfortunately, that doesn't always work. In addition to the above, many governement oversight programs are underfunded or have had their power legistlated away. On top of all that, companies aren't always upfront with letting an inspector see the normal daily operations.
Ancedotes I worked as a CNA in a nursing home. They were commonly understaffed. This is fairly common with nursing homes in the state I was in. There was a state agency that checked such things, but it seemed the nursing homes always had a notice when they were going to visit. Suddenly, they had a lot of manditory and voluntary overtime available and stuck to the rules. If the visits were sporadic, more often, and they checked things like logs and historic staffing levels, I'm guessing this would change. I think the only way to get this improved would be for enough private activists to gather evidence from many different places and get state laws changed after making a public outcry.
Ancedote 2 I worked in a food factory for a day or two. Now, they were horrible employers for various reasons, but the facility was clean and there was a lot of focus on meeting food prep safety guidelines. In fact, there were USDA employees assigned to that factory, and they could not run without it. Actual oversight. But food factories might not have been like this had it not been for private activists, and it still isn't perfect. One still hears horror stories in small towns with a meat processing plant, for example, but I have no clue if they are true or not.
