Whenever I hear ‘advocates’ and government officials tinkering with word usage to advance a political/policy cause, George Orwell’s ‘meaningless words’ warning jumps to mind. … The “millionaires’ tax” is not the “Fair Share” tax, folks, despite what surtax proponents and government officials tell the Globe. … When you think about it, calling it the “millionaires’ tax” is probably why the referendum passed in their first place. It was a pithy, down-to-earth way to describe a tax on those making at least 10 times more than the median household income in Mass.
