Unless you can explain why the American stumpage fees are inherently "correct", this is simply a case of one country having a bigger supply of something and therefore being able to offer it much cheaper. You know... Capitalism working exactly as intended.
Isn't that kind of America's thing?
"No, not like that!"
All the rest of this is designed to distract from the real issue: Americans love Capitalism, except in the rare cases where they don't come out on top. Then everyone else is being mean and unfair.
It's funny. When European governments charge high fees, Americans deride them as socialist and anti-capitalist. When the American government does it (as it does here)? Why, it's the natural order of things! Our fees are the "correct" fees. It's everyone else that's wrong!
Please.
