My world(s) tend to be very dark age, very migration period. This is regardless of technology. Community matters, your word and deed matters and people tend to be accommodating of strangers. If you are a decent and capable person you can find acceptance in whatever community you desire. A wandering stranger can find their way to the upper echelons of communities. Outsourcing is then now that I think of it kinda common, but with the goal of bringing whose doing the outsourced task into the community.
