E.E. 'Doc’ Smith 
Subspace Explorers [EPUB ebook] 

This is an expansion of Smith’s story 'Subspace Survivors, ’ containing a three-part theme: A space catastrophe and its results; the discovery and scientific study of psionics; and a war between the corrupt and shortsighted (including Labour, politicians, Sovietstyle communists and greedy capitalists) and those who can see a bit further (mostly tradesmen, professionals, and businessmen).
Blended together by an author called the 'Father of Space Opera.’
