No, I would say it does not.  Walter Jon Williams' [*Voice of the Whirlwind*][vw] takes place in and around Earth, but the main character, Steward, was previously a soldier deployed to a corporate colony in another star system, where he fought in a war against other corporations until the planet's owners, The Powers, came home and kicked the human corporations out.

The Powers have basically restricted humanity to the solar system (in the story's present) but have 2 stations in the asteroid belt for commercial and political dealings.  So in this setting interstellar travel is definitely possible, and humans have done it.  I don't recall any description of _how_ it works, so it may be sub-light.
