After the recession of 2007-2009 many people pointed to Ayn Rand's Atlas Shrugged as a book that depicted the situation we found ourselves living. Outside of the space aliens and travel I think the LaNague Chonicles deals with an oppressive government in a more realistic fashion. Peter Lanague pushes the government to the limits and let's them fall over the tipping point.
The LaNague Chronicles Is actually a series of novella length stories written very early in Wilson's career, late 60's early 70's. The political intrigue while intertwined through the whole saga is really only a major part of one story.
While I found the Chronicles to be an enjoyable read be fore warned it does have an unsatisfying ending
