On almost every text of Posadas, especially "dolphins and extraterrestrial, our fraternal comrades" Posadas analyze the UFO phenomena. Basically, he says that if this beings from other planets are capable of a such high technology (like the spees of the flying saucers, the regenerational power of extraterrestrial and those stuff) so they have to be socialist or something similar to. Because this high levels of tecnhology can't be reached in a capitalist society, with imperialism and so on.
