Then it isn't the copyright at fault here but the agreement between the artist/author and publisher. Artists are famously forced to make bad deals when they don't have any leverage.
Despite how many negatives the current copyright regime has, having to wait 70 years after the death of the author is far too long of a timeframe for that strategy to play out.
In that case, by definition, the artist was paid.
Being paid for a spec or a per diem while making the movie can be peanuts. Big name actors and writers make percentages on the backend.
This seems utterly arbitrary. I fail to understand your logic here.
Artists would still make art but would have to either have patronage or find an alternative income source to make a living.
There. Fix't.
The artist has no sort of guarantee of income from any particular piece of work or really even subsistence from their entire life's output of work.
I think most people would agree that the physical trades and the arts are not well-suited for comparisons. They are just fundamentally too different.
How is the writing of a book, the production of a movie or the recording of a song any different from the building of a bridge, the drafting of a contract, or the provision of management consultancy? How are they "fundamentally too different" if it's not the way we pay for them?
But more importantly, how is is that we see this difference as so fundamental that we afford protection to an artist (or more accurately, their publishers and the industry that surrounds them) via copyright for so long?
You do not get to clone the shovel by magic for about .1 cent and sell 50M copies of it for $20 each for the next forever.
Again - the copyright system as it currently exists needs to die. 7 years protection is enuogh.
The point was not to defend the current copyright system and certainly not some of the more notable abusers. You asked a question, and that that is one part of the answer. Writing a book or doing any form of creative information-product work is different from doing physical-product or service work.
If you want to make money, open-sourcing your work seems to be a very hard way of doing so.
