People will whine about how the French government should not tax stuff to support local culture.
But any movie produced in any country larger than France (for instance US, India, China) can be paid for in the local market and then basically given away for free or as close to free as needed to kill the local production.
Add to this that the US is rabidly promoting "patriotism" which is a form of nationalism so that anything "foreign" is automatically suspect.
The various programs promoting this are ways to close the US market against "foreign influence".
(And BTW US "Patriotism" is being "Proud of being American", and unless you are a wet back Latino who on peril of his or her life crossed the border illegally than worked for many years with fear of deportation in his or her stomach and then finally get citizenship it is being proud of being born and nothing else.)
So the market is "not free and fair", and taxation is one way of offsetting the fact that it is inherently easier to make money when your market starts with 400M citizens instead of 65M.
And it is "nicer" than resort to propaganda, like forcing small children to "pledge to the flag", militarization of the society and such things.
And to finish, you can play a "fun game", look at "family oriented" blockbusters and try to read the "sub text" and what it says about your society.
