For starters guilds tend to have progression by merit, requiring an apprentice prove they are competent enough to be considered a journeyman.
And you know … not wanting to be exploited… healthcare sounds nice… ( on this point, I’d like to point out that as an Australian software engineer, I long ago resolved to never start a company in America because of how insane healthcare in America is. I can understand the guns, the polarised politics and all the rest of the things that make America what it is… but healthcare is just so fucking insane that i haven’t even seriously considered taking a holiday there to see the museums that have been on my bucket list for half my life… the idea of starting a business there is just an immediate non starter… I’ll take US cash and setup a holding corp if they demand US incorporation and employ people elsewhere… so having a guild where healthcare was provided would make American developers more competitive in the job market)
