alt Hacker News> mobility is a privilege
We made it a priviledge, but for a biological being, it's the most natural thing to do when you find yourself in a place that is shitty. There is a reason so many risk truly awful things to get a chance (chance!) at a better life: going to where food and safety is, is just what living beings do.
Sure, but I think what they mean is that when you do move somewhere, how you are treated by the humans already there depends on your socioeconomic status. Who may be disinclined to let you have food or safety.
