It's a fair question. Greenland appears to be a very harsh place to live. Younger generations may not want to deal with that and go live in Europe.
Since Greenland is part of Denmark, Greenlanders are free to move to Denmark. There are 16k or so, but can't tell how many are Greenlandic or Danish heritage.
Greenlanders are EU citizens and can move quite freely in Europe, not just Denmark.
Does the American government pay people to post and push their narratives on the internet?
They don’t have to. People will do it for free if you promise
to cut their taxes and social services.
Some people don't mind living close to nature, but rather see that as a positive. And many people seek out the same environment they grew up in, as they are used to that. Isn't it like that where you live?
Your question is not an unreasonable one. One fifth of all Greenlanders live in Denmark.
