And they kept saying "I didn't want to uproot my family blah blah." Is there no value in exposing your children to unique and different experiences? I'll have failed if my kids grew up in the same town/city all their lives.
My dad worked in the oil business in the 80s and 90s and spent months at a time in places like Saudi, Norway, etc. In hindsight, I would never have wanted to move around with him as a kid. Sure I would have liked him at home more, but at least we all knew where home was.
we want our daughters to have exactly that, it's great to see our 2-year-old make friends that she could reasonably expect to finish High School with, and that might even last a lifetime
I grew up in a family that had to move around a lot, to the point where I attended 3 different elementary schools, 2 different junior highs and 1 high school. We were not rich but poor. And I SO WISH I had grown up in same neighborhood so that I could've have made some friends in my childhood.
You can go live in different towns/cities when you are older. For kids, I highly recommend for kids to have stable environment with mostly same friends at least until college time.
Anyway, you might feel disconnected. I actually was disconnected, multiple times, from my friends, environment, and had no other possibility but to start from scratch. So I don't even understand why you feel the need to compare, to be honest.
you're not doing anybody any favor dragging kids around the world because of your crappy career goals, it's just being selfish.
If you want to be super good parent, take them each year for a month long vacation somewhere far and exotic (ie very different than their usual environment), that's more than enough.
