Unless you mean state or federal law, that won't do anything, because "The problem is that they are often willing to ignore an area until they get the concessions they want." Wal-Mart will just not build in SmallTown, Arkansas if they have to spend twice as much as in LittleTown, Arkansas 5 miles down the road. SmallTown can put whatever requirements they want into the law. Wal-Mart just won't build there until they change the law. Of course, whether SmallTown should want Wal-Mart is a valid question. Unfortunately, they probably do, because Wal-Mart moving into LittleTown will probably decimate the local retail economy anyway.
