Home is difficult to define.
A couple, that I'm really good friends with, moved to Seoul from Texas for 2 years last ~July. They've taken their two kids and are totally exposing them to as much as possible. The couple (not the kids) just left the cold snowy winter weather of Seoul for a week in Maui. They hit the beach, they hit ziplines, they hit whatever. They relaxed, probably drank too much, and then probably also had some "quiet time".
Upon returning, as the plane was landing in Seoul (oh, they are rather tall white people), the wife said to her husband- "It's good to be home."
They aren't Korean, are definitely returning to the States in 18 more months, and their "energies" are in the US as well, most notably Texas & California. (Talking about "energy" is very California, I understand.) But they still feel like Korea is "home" at the moment.
There's no need to judge where people find themselves in life. (Unless it's San Telmo or certain parts of Palermo, because they're delusional.) I could live here the rest of my life, or something could happen that could change all that in the blink of an eye. If you can afford it, life is easier in the States than here. Probably easier than almost anywhere in the world. Some people run out of will/fight and don't want every day to be a challenge.
Just a little tired, and don't blame people for wanting conveniences & respect in their lives.
