Right this minute it would make more tax sense to have almost all commodities markets on the lower Mississippi. After tax reform it will make much more sense. Other than a decent party town and a nice view from the Mansion the stock market could be located almost anywhere in the US where picking up starlets and wannabe models is easy. An actual opera house or two and a theater district in Nashville would do nicely but so would 30 or more other locations would also be in contention as acceptable relocation points. How long will it take to happen?
