For regulations that have low cost and high benefit, the costs are often borne by few people, but the benefits are spread among many. Those who bear the costs scream loudly; those who reap the benefits may be mildly grateful. And those who bear the costs try very hard to make this regulation look like it is high-cost and low-benefit.
And the same is true in reverse for regulations that are high-cost and low-benefit. Those who receive the benefit try very hard (and very loudly) to make it seem that the regulation is low-cost and high-benefit.
This can make it hard to determine which kind of regulation is which, even if you genuinely want to. But regulations are political, and politicians care about votes, not necessarily about costs and benefits. As long as the narrow interests care deeply (and vote accordingly), the politicians are not likely to care about the wider interests.
Some regulations have low cost and high benefit. They should be kept.
Others have high cost and low benefit. They should be removed or reformed.
