Remember, a lot of the "West" (at least my exposure to it, the USA) is a conglomeration of other cultures; we have many Eastern cultures here as well!
Many of my friends have large families that they're much more entangled with than I'd opt into with my own family.
I could not live with my mother again, though I love her very much. I imagine many Indian men would love to have that option, all else being equal, though realistically they simply don't.
The freedom to choose is nice, but a great many of us "Westerners" choose to stay close to our families. That's what freedom is; the ability to opt into culture, rather than be forced into it.
