So, my understanding is that law firms have the structure they do in part because there are legal restrictions that say that law firms must be owned by lawyers, not just by any old group of shareholders. Ostensibly this is supposed to be about professional ethics. But so structurally, ownership is reserved for people who are at least in principle involved with doing the actual work of the firm. I wonder how engineers would do with the same sort of structure? If tech firms had to be owned by people who actually participate in creating tech, how would that change us? And how would it change what we build?
