Doctors, actors, pro athletes. There are many types of guilds and professional associations beyond unions.

Furthermore, if tech is about disrupting everything, including the nature of work itself (through on-demand) and even the nature of human relations itself (through social media), then surely some attempt could be made to better labor relations by inventing a better type of union. It's especially rich to hear "no, it can't happen, it's always failed in the past" comments wrt labor unions come from workers who work in an industry that's supposedly all about innovation.

I wasn't trying to attack you for your original comment, in any case. You actually offer good advice. But my general sentiment is that we shouldn't try to restrict the labor market- it seems as wrongheaded as trying to fight gentrification by limiting house construction just because some of those units will be luxury condos instead of affordable housing- and that lowered wages could be fought by the presence of a tech union that protects tech workers.
