product liability truths are a third-rail in market capitalism
translation: mass market products are responsible for a very large portion of the total economic GDP, and by definition, touch the lives of millions (or more) people each day. Product liability is a system of law where the brand holder does have financial responsibility when things go wrong. Truth, obviously, is the real effects of the products on people, living things, and our common environment. A third-rail is a real-live, high voltage carrier of power for trains, but the term is used to convey something too powerful to even slightly touch, at the risk of death and destruction. In colloquial political talk it means that a appointed official or elected official could be terminated by broaching the topic in public.
from an "Economist magazine point of view" some products do cease to generate profit after restrictions or penalties on the market, which is "deadly" to profit.
depending on your world view, many products today, like gas-driven cars, are actually toxic from the beginning, yet have so much economic and daily importance that it is collectively tolerated, until it is not.
ordinary product liability, like "body burden" long lived chemistry rubbing off from sofas or children's toys, live in a gray area in markets where a change in public opinion or regulatory framework can alter the product and its market quite a bit at any time.
since steady profit over time is a de-facto definition of social power, there are multiple layers of second or third order actors that delay, deny and obfuscate any change in status quo, and are paid real money to do so.
activists, educators, researchers and regulators that try to change the status quo of products with facts about toxicity are then "touching a third-tail"
