That would be a radically dangerous position to adopt. It is exactly the position which fueled colonialism. They thought they had grown up as well and were in a position to 'help' the rest of humanity grow with them - into being driven primarily by economic motives dedicated to suppressing every counter-productive urge to pleasure that humans experience. And, of course, the Holocaust was supported by this exact argument as well. We'd developed enough that we knew how to improve the human race - eugenics. We knew how to improve 'mental hygeine'. All that was required was hard men making the hard choices, overcoming the weaknesses of empathy and compassion for the greater good. And the people lapped it up. That is a dangerous area to tread upon. We should always be humble in our knowledge, and parsimonious in its application.
