I totally agree with this. A union may not be necessary in many cases, but some sort of organization definitely is. Many of my examples have self-organized, self-regulations associations that manage their own credentials and establish rate guidelines for their services. Other professional pools should learn from this.

I've been advocating for guilds for a while. The software industry should learn from the actors. It's artistic work with a labour pool comprising of vastly different capabilities, yet they managed to find a way to band together. Moreover, exceptional talent is still compensated above and beyond, unlike a union: Being part of the guild does not restrict the likes of Tom Cruise or Margot Robbie from being paid buckets of money, getting a gross of the profits, etc.
