Having been to Iceland I think there’s a number of reasons for that. Iceland might as well be New York City compared to Greenland. The settlements are significantly larger, meaning there’s more stuff to do. Greenland, due to its isolation and harsher climate, has higher prices for goods and higher poverty rates.
Greenland doesn’t have as much infrastructure for local affordable food production and doesn’t have as stable an economy. Greenlanders are also having to deal with the disruption of traditional lifestyles, which carries impacts on the older generations from resettled villages. Canadian Inuit communities face a similar issue of suicide rates.
