The huge costs of state and local taxes should be a major factor.
Why did Carrier shut its factories in Syracuse, New York?
High income taxes. High property taxes. High nuisance taxes.
The CEO of Carrier was asked to name specifically, in a news conference, which taxes and regulations were the leading cause of their impending move to Mexico. He couldn't name any. Also I am still waiting for that same CEO to proclaim price reductions for all AC units made in Mexico...
