Michael Mandel, an economist at the Progressive Policy Institute, compares many regulations to “pebbles in a stream.” Individually, they may not have a big impact. But if there are too many pebbles, a river’s flow can be thwarted. Similarly, too many regulations can limit business activity. When the number of rules mounts, it can become hard for a business to know whether it is operating within the law’s confines. The issue is all the more problematic when federal, state and local constraints all apply.
