Eli5: Why did civilizations such as the Pre Dorset, Thule, and Inuit not migrate south if their environments were so harsh and extreme?

Question

I read a few articles where some of these civilizations main focus was keeping warm because they were located so far north. So why would they not migrate more south?

Answer 1

It’s a function of power. More powerful groups occupied better regions. Less powerful groups were pushed to the less hospitable regions. After a time cultures developed allowing the survival in certain inhospitable regions.

One had to be careful not to stray too far outside your territory since there was a good chance those folks would kill you if they found you.
