Can someone help me to understand: why is a bill needed for this? Don't "company towns" already exist? Were they illegal somehow? Would it be illegal to build one now (in Nevada, without this bill)? Or is this proposing something besides a regular "company town" model (i.e. a regular municipality where everyone who lives there is an employee of company X; and there are municipal elections, but all the options on the ballet are, of course, employees of company X; and where the elected government contracts out many services to... company X)? Is the idea here that the corporation itself would be the municipal government, rather than the municipal government being a regular elected body consisting of company-X employees? If so, would that not make the election for the corporation's board of directors, a municipal election; and somehow create a link between landholding within the incorporated land area and shareholding in the corporation?
