Some, and I think its growing as we see less classic space western and space opera. Swords and Sorcery in space and science fantasy like to go this route but typically with single planet solar systems. Military sci-fi tends to explore the political backdrop more too, and often goes the aristocrat route I've noticed, it lets them use the warrior tradition route more and avoid the WMD problems, essentially that any culture than can colonize other planets has no problem torching one in mere moments without ever landing troops, making for a boring story.

When we start getting into simulated realities as the daily norm though, that more or less murders any subdivisions beyond top level and individual. Someone is making sure your brain in a vat, whole body, or the hard drive you're stored on is maintained, and someone is making sure the electricity and raw materials and network keep running. The difference is the location of your body isn't really very relevant to who you interact with in terms of normal society, where you can't pick your neighbors. Even a work-from-home person who is a total shut-in isn't nearly as severed from their physical community as that and more to the point wasn't raised a shut in nor exposed to entertainment where that was the norm. You'd have a very, very different culture I'd think after a few generations of people who had basically always been able to instantly leave any environment or interaction they found even vaguely boring or hostile. You're not very likely to have much in the way of classic political or national situations going on there or any real parallel analogy cases.
