From the outside, it’s accomplished via private interests bending the regulations in their favor, which is why we have a term for it: “regulatory capture”.
I’m not sure what your point is. Are you still stuck on the incorrect notion that “regulatory capture” can be summarized as onerous regulation? That simply does not work, but I’m happy to keep trying to explain why, if it’s not clear yet. There are also plenty of cases of regulatory capture dismantling regulations for everyone. Again, the single most relevant case in this thread, of Boeing circa the Lion Air crashes, is one of removing regulation. No regulations were made onerous or unnecessary in that case, it was the opposite of that, the regulation was bypassed for Boeing’s benefit, effectively removing it, and it remained unchanged for other carriers.
When regulatory capture occurs, sometimes regulations get harder, and sometimes they get easier. Whether it’s one or the other depends on the case, and depends on whose perspective it is. Trying to summarize “regulatory capture” as making regulations harder is just false, because that’s not what always happens, and not even what usually happens, and it completely fails to mention the primary relevant point: the special interest getting prioritized over the public interest.
