This is the one thing that kills me with one of my favorite space movies, interstellar... they have that one scene at the school saying the landings were faked to bankrupt the soviets...like how the fuck did that make it into the movie.
It's not there as some commentary by Christopher Nolan that the moon landings didn't happen. It's there to show that schools are willing to teach a lie as long as it serves the narrative of "past oppulence is what destroyed our world, so get out there and be a farmer!"
O damn never thought of it that way. I went and looked it up further and you're spot on, it seems it was put into the movie to make people become farmers and not look to space. Basically try and solve the problems on earth.
