Capitalism Allows This: 97.3% Gross Profit Margin; Should There Be a Windfall Profits Tax on This?
According to Box Office Mojo, Michael Moore's movie "Fahrenheit 9/11" had a worldwide gross of $222,446,882, with a production budget of only $6,000,000. That's a gross profit margin of 97.3%, and a gross return on investment of 3,607% (not all for Michael Moore, since there were obviously distribution costs and payments to theaters, etc.). Not sure if that sets any kind of profit record for a movie, but it's a pretty impressive, eye-popping profit margin and ROI, and the kind of capitalist return on a movie that a Cuban filmaker would only dream about.
Update: As MJD suggests in the comments, perhaps Michael Moore should be investigated for making "windfall profits" on this movie.
