1) Distribution is where studios' value-add really comes through: they're the ones who have contracts with the big theater chains (or, in the case of tv, often own the networks+streaming services) and are in control of the dates/weekends/IMAX exclusivities/etc.
2) Financing - Movies and TV are _expensive_. It's not just the high-profile actors or marketing budgets – indeed, many high-profile actors will take huge pay-cuts to work on passion projects – but, if you were to take away those costs, and for sake of argument let's say that everyone acting/shooting/editing the movie is working for free, there's still huge capital expenses to be outlaid: location fees, permit fees, cameras (even a single indie-film camera can be upwards of $50k), sets + construction, props, editing+vfx software, food, transport, clothing, makeup, logistics and infrastructure including things as fundamental as electricity and plumbing if you're filming anywhere that's not a backlot... It takes a huge capital upfront outlay to make a movie or tv show that looks anything like what we're used to seeing on tv and movie screens. Studios can (a) provide the upfront cash and deal structure such that financing the productions is feasible in the first place (b) re-use and cost-optimize everything from sets/space/cameras/software/support-staff across productions where it makes sense, so a show or movie isn't having to re-invent everything from the ground up each time.
The closest right now the WGA or SAG can possibly be to "creating their own movies" is working with an indie studio, like A24 or NEON, who are still very much studios, but often with a more "can-do" and "per-production" approach. These studios also settled with WGA and SAG very soon after the strikes began, and were granted strike waivers so they could continue production, while the Disneys and Netflixes were picketed.
In short, unlike software engineers where a single dedicated engineer can pretty much create an app or business mvp in a weekend, writers and actors deal with the constraints of the real-world.
Unions ironically act very conservative these days. They could take some bold steps to potentially create very worker-friendly, worker-owned shops, which would create a voluntary, non-coercive path towards the "market socialist" structure many people advocate.
Even in large industries like automobiles where this is hard, they could probably start doing something like smaller-scale parts production and sell those.
Because that requires skillsets they don't have. People with the skills to start, manage and run companies usually aren't workers so not a part of the union, and I doubt the union members would be happy if the union spent lots of money to hire managers to bet on a startup.
This is reductive, union organizers have management skills that would transfer over if needed. The reason co-ops are not more common is moreso because there aren't the same kinds of institutions that support their growth like there are for traditional companies.
In practice they have just been another layer of economically unproductive people siphoning off value.
Word.
IIRC: SEIU, or equally large org, has been funding employee co-ops.
Also IIRC: Richard Wolfe coined worker directed social enterprises (WDSE) to encompass all the democracy and co-op notions.
Having done some (very modest) workplace democracy, and seen the results, I'm very bullish. I read Wolfe's book Democracy at Work when it came out. It was a (very modest) good start. But needed a lot more work developing the ideas. Especially wrt governance and operations.
Enough time has passed, I should circle back and see how things have progressed.
> Unions ironically act very conservative these days.
In multiple ways.
In the US, the transition from representing predominately white middle class blue collar workers to representing all workers has been very bumpy.
Labor in the US would be so much further along today if unions had also abandoned their commitment to the Cold War Consensus when Capital did. Anti labor measures like NAFTA should have been wake up calls.
Edit: the other instances (much fewer) are when the company founders either start with a co-op in mind or want to transition their company to one as part of their legacy
