What good did the moon landing do for the average man?

Directly, immediately? In the 1960s? Aside from the people employed working directly or indirectly on space efforts? Almost none. Is that really the answer you're looking for, though? Scientific knowledge can take decades or even centuries before it improves our lives tangibly. But I think you know that, so I won't argue with you about it.

Concerning the waste of time, money and attention - LOL there was the Vietnam war, too. I'd argue was less beneficial to humanity than Apollo. I am only raising this point because I think it's unfair to place blame for lack of social progress at the feet of scientists, or a sub-set of scientists. We're collectively responsible.

Otherwise, I generally agree with you. The Apollo program was not conceived or executed to benefit science. But Apollo did mobilize science irrevocably. "Planetary science" as a discipline, community and way of thinking didn't exist before Apollo. Very few people, even in the science community, were comparing planets and learning something from that before about 1970. Ditto for environmental science - and that community, too, barely existed before Apollo. Even though that field got a headstart due to people like Rachel Carson.

Would you have improved social conditions for anyone by cancelling Apollo/Gemini in, say, 1964? I'm not so sure about that. 1968 certainly implies otherwise. I'm here to tell you that exploring neighboring worlds is a social good because you learn the parameters of your own environment, parameters you MUST keep an eye on to keep Earth habitable. But that social good is a joke if people can't walk down the street without worrying about ICE raids. So yeah, you're right, racial hatred obviates this beautiful and essential realization that we're connected to a bigger universe. Would you have the scientists of the world hide their knowledge away because we live surrounded by ugliness? All I can say to you is that we live here too, and this fight is ours as much as yours.
