I'm a big fan of contextual laws with expiring timelines. One size fits all laws that are used like hammers for every industry and every company size are very destructive (the positive data supporting things like minimum wage laws are almost always limited to a few industries like mega-chain fast food restaurants, while there is plenty of evidence of harm for young and temporary workers). The conditions of marketplaces also constantly change where expiring/renewal should be a function of the policy.

I don't know, we don't have these sunset laws, they seem like an inefficient, because they lead to too much change without change in the environment. And become big rallying points to either keep them afloat or finally get rid of them. This of course could drive compromise, or just lead to a lot more tit-for-tat destruction. (You let expire that, now we'll let this one expire!)
