I don’t understand your comment. Do you not know what a pipe-fitter is? What about the trade strikes you as a larp?

I’ve never been to lunch with one, although my son worked as a welder’s helper at a pipe-fitting company.

The larp is that software unions are anything like blue collar unions, and that socialists want to selectively act as the voice of blue collar when they are in a completely different class and do not interact with them.

I’ll note one key difference. Software output and skills vary on a power scale. Blue collar work is often heavily defined by formal procedures and codes so that trained personnel are largely interchangeable from a business perspective (not always or completely true). So without a union it’s a constant race to the bottom because the labor is fungible and the only requirement for success is passing minimum criteria.
