[Boatanchors] More question on US AC voltage

Don't you think it is in the monetary interest of the electric utilities 
to keep the supplied voltage on the high side of nominal?  If I recall 
Ohm's law correctly, as voltage goes up, power increases as the square 
of voltage (P = E squared /R).  In other words, as an example, if the 
voltage is raised 4%, the power consumed will increase 16% assuming R 
remains constant.  Increased consumption = higher power bills = 
increased operating profits.
