I am saying that running your own show or a show with other people you value working with does not need to be under the thumb of union rules or overarching corporate pressure.
There is no scenario in entertainment where unions "keep to themselves". A union started will soak up the entire industry and now my show with people I respect, admire and fair equity shares now has time limits and controls none of us decided or agreed to because a union(s) can excommunicate us from the entire working industry.
The industry should self-regulate under threat. Implementing a union will benefit few but the union leaders. The film industry is a prime example of what happens and films like Star Wars barely exist in the face of union pressure. George Lucas hired Irvine Kershner to direct because he knew all about Hollywood, but was 'not Hollywood'. Gary Oldman turned down a SW role due to union rules. The public has no idea how cliquey and regulated the film industry is, thanks in part to the studio model and union rules.
I'd sooner call for a tech union and see a whole bunch of engineers get a proper cut of the $100 million+ companies that get sold without them seeing a dime.
Game industry artists are very skilled and can get work elsewhere for much easier conditions. They choose to stay and work hard and can choose to negotiate better salaries. I can't comment on mega-corps that there are limits to negotiations, in the independent part there is a lot more leeway. The conditions will always be difficult, timing is the difficulty that we can't control.
