And by in-space economy I meant one where there are bases (from science to mining) on the Moon and Mars, space stations (for scientific, residential, manufacturing, etc.) galore around Earth's orbit, maybe the beginnings of some prospecting in the asteroid belt for mines from some companies/nations. I'm not a history or politics nerd by any means but I think (in my very uninformed opinion) had NASA's budget not been gutted by succeeding administrations, more incentives for companies to go to space, greater collaborations w/ different space agencies or just having a good political will to keep getting to space in the years after the space race might do but I'm curious to see what others think.
I've been using this as my main resource: https://www.factoriesinspace.com/graphs/In-Space-Economy-2021_Erik-Kulu_IAC2021.pdf, which talks about all the stuff that an in-space economy should make up (commercial space stations, commercial human spaceflight, in-space manufacturing, surface bases, asteroid mining etc.) [don't really know if that's relevant to determining PODs (Points of Divergence) but I thought every little bit helps for clarifying].
So, what I meant to say after all that jumbled mess of words is: what are possible divergences in history that can lead to an accelerated progress of Earth's nations having an in-space economy?
