I think it's the exact opposite problem the tech industry has.

The film industry has way more talent supply than the employment demands, which naturally suppresses pay. The guilds/unions are a way to increase scarcity to maintain pay and ease hiring.

The tech industry has much less talent supply and much much much more employment demand. Tech might be better modeled after high skilled trade unions (which have a labor shortage) than the comparatively lower skilled film/auto/factory unions (which have a labor surplus).
