The neat thing about post scarcity societies is that economic systems become moot so long as the government isn’t particularly oppressive. It’s still an hierarchical, and somewhat militaristic, society.
It also followed the old scifi serial blueprint they were used to.
To add to #5: safety margins are kind of nuts on airplanes. I want to say a lot of mentally deficient rednecks build airplanes, but that’s confirmation bias. Most of them are decent. Even then, safety margins, quality standards and procedures are made to account for morons and cowards that don’t want to admit they fucked up. The critical bits are done with even higher standards.
They’re safe as fuck. I’ve been in the industry for almost 20 years now and I love flying. When the plane first banks after take off and the whole airframe creaks is my favorite part, even. Fuck you nature: we fucking win.
The thousands of people across the globe that were involved in building the plane you’re getting onto are proud of what they do and genuinely care about your safety. Smile and tell gravity to suck your dick.
