yeah it's a very cool idea. you should read the book anyways but if you are interested in a "leftist language" it is one of the only examples that I know of from fiction. some things i remember from it:

-all names are randomly generated and are not gendered

-personal possessives are rarely (never? been a few months since i've read it) used

-the equivalent of "hell" has evolved to refer to waste dumps rather than the theological concept; characters are surprised to find out the religious origins of the word

probably a few more neat details through there. the book isn't about the language and as far as i know le guin didn't go as crazy over it as some other authors do for their conlangs but it's a good book regardless
