What do you think of Hugo Chavez's theory that capitalism and imperialism was the cause of Mars' demise?

On a recent speech, Venezuelan President Hugo Chavez suggested that Mars actual condition was likely the cause of a society driven by capitalist and imperialist ideologies. Scientists have always theorized the idea the Mars was once a planet similar to ours; harboring life, vast oceans and vegetation. Somewhere down the road, all that went away and recent research have suggested the planet may still be alive to some degree considering there may be water present. On his usual rhetoric about United States policy, Chavez suggested that we might as well see Mars as a reflection as to whats coming ahead of us if we continue running our world that way we do and, of course, he couldn't help directing his thoughts towards his opposition and disapproval of the United States.
