I think not. European colonialism was hardly a democratic project, and the extreme success of the US is attributable less to ideology and more to being an entire continent with a relatively tiny indigenous population that had not exploited any of its natural resources. Ideological/paradigmatic competition is not some neat controlled experiment where you can normalize existing conditions to unity and then draw conclusions from measuring subsequent growth; initial resource distributions make a massive difference and geography, while not the only factor, is highly determinative.
