Many rockets continue to fly to Mars, bringing ever more men and women settlers. However, all of the rockets come from the United States, so all the settlers are Americans. The rest of the world is at war and does not go to Mars.
Going to Mars is exclusively an American right. Bradbury does not explicitly say people from other countries wanted the chance, but he implies it by stating they "watched the roman candles leave them behind." Since roman candles are fireworks and fireworks symbolize excitement, it follows that non-Americans would have rather gone to Mars than be "buried in war or the thoughts of war."
Instead of the second wave of settlers bringing "other ideas" to the colonization of Mars, they are the oppressed class of Americans from the "cabbage tenements" and other such places who are susceptible to the government bureaucracy that Bradbury disdains.
