Tech workers used to not be average people.
Could you say more about the differences you see between a traditional US union and a modern day guild?
In the US, doctors, lawyers, and to some extent professional engineers and other licensed professions operate under a somewhat similar model in that they restrict supply of that class of labor through some sort of accreditation, apply minimum standards for the profession, and otherwise stay out of your business for the most part.
Of course, simultaneously, they treat us as completely fungible. Every engineer is like any other in their eyes.
Such a perfect contradiction should surely spark introspection in employees... you would think.
