Not evreyone can invest in SpaceX. More capital isn't always the best thing or necessary and it still involves a lot of risk. This is just an ignorant comment imo.
That said I'd love to buy some SpaceX stock if only I could!
I don't specifically mean why isn't more money in SpaceX in general, I want to know why there is so little money and companies actually innovating in important hard things like space, clean transportation, clean energy, etc.
Imagine if as a global civilization we'd invested the two trillion in crypto into clean energy instead. We might actually solve our pressing climate change problem. Instead we got digital coins and NFTs and actually made the climate change problem worse.
