That's the double edged sword. Requiring labeling doesn't prevent label fraud, and pretending label fraud is rare is either naive or obtuse.
Oversight is then called for (eg USDA organic) which itself can still be frauded around, especially when dealing with sources outside of the US.
I'm reminded of a tiktok that had raw chicken labeled with a particular weight at Walmart. When they weighed it on a checkout scale, it didn't match the weight the label had. On multiple packages.
> just want the label to tell me what's in the product
You will never, ever get that. It's simply impossible. Label games are the biggest legal tug-of-war between consumers, regulators, vendors, and the industries.
When I began reading about labeling and its regulation, and all the bullshit tricks that are played to "stay compliant" but also lie out their asses to the consumer, and hide everything from us, I concluded that there is no way to truly read a label properly.
It basically comes down to a question of whether you trust this vendor or provider to give you a quality product. If you do not trust, then do not purchase. If they play games and lose trust, then do not purchase. Once you have a decent-sized blacklist, then there is no reason not to patronize those survivors.
