I was exaggerating. Sure they're regulated, but "heavily" is also an overstatement compared to how much they should be regulated. This is no different than how when talking about installing a new pipeline they say there's all these fail-safes, protections, monitoring, inspections, etc, but then oil leaks happen and it's found that the pipe had been deteriorating for months if not years which shows they actually aren't under the scrutiny that's claimed and there aren't protections in place. Or they lobby to have their pipeline self-inspected similar to what Tyson was able to negotiate with their meat plants. That's just one example of many. Sure in theory there's all this regulation, but somehow we keep having disaster after disaster that would have been avoided if all these regulations were enforced.
