The current POTUS made a campaign promise that he would only allow a regulation to be added if two more were eliminated. This is asinine. If there are unnecessary regulations, get rid of them. Get rid of them because they're unnecessary or counterproductive, not because they fall into a category of legislation referred to as "regulations". Losing a regulation isn't an inherently good thing any more than gaining one is an inherently bad thing. The only thing that matters is whether or not it's a net positive, and that's specific to each regulation. It's like saying, "there's too many laws! We need to get rid of some laws!", and proceeding to randomly choose laws to get rid of until numberOfLaws <= totallyArbitraryMaximumLawCountThatSomeoneMadeUp.
Fewer, well-chosen regulations with very strong penalties that easily pay for strict enforcement activity - that's much rarer; and I'm cynical enough about how gets to influence lawmakers, that I know why that is.
