The world population also had an attachment to its land but were uprooted and transported and mingled and spread all over the world and has resulted in significant economic development. Get on with the program , it is the new reality.
My large, tightly knit family emigrated in the last generation (to Canada, the US, and Australia) and it was devastating. We went from living in the same city to living on three different continents. Life is materially better, but there’s no replacement for kinship ties.
I think my mom never really perceived it as an upgrade. My dad did, but as he gets older it’s getting tougher. Professional networks disperse, and he doesn’t really have family in the country. His relationship with his brother (who actually immigrated to NY recently) didn’t really survive 30 years of separation. My kids will probably never meet all of their cousins.
I totally get the folks in rural Ohio that don’t want to emigrate to the coasts for jobs. They’re going to be facing significant disruptions in their family networks. And it’s not like they’ll enjoy a quantum leap in living standards and social status elsewhere. They’ll just be at the bottom of the totem pole somewhere unfamiliar.
