WEF cites a global space economy at $630 billion, alongside investments of $70 billion. [1] And as anybody with half a head on their shoulder can see, space will be where the big future economic growth will come from. Even if somebody has 0 interest in space, which I think is
very few people, that's where the next 'big boom' in economics will come from. And SpaceX was started on a fraction of $0.3 billion with Carmack and Bezos just being a couple of names people on here would be familiar with, amongst tens of thousands. Yet no competitor is anywhere to be found.
And the US doesn't have a long history of aerospace innovation. In 1962 Kennedy gave his 'to the Moon' speech, 7 years later in 1969 we'd go from having nothing to putting a man on the Moon. From 1969 (well 1972 in particular) to the birth of SpaceX (early 2000s) US space technology not only stagnated but regressed. This is why Boeing (who was a major part of the original space race) can't manage to even begin to replicate what we achieved in the 60s, in 7 years no less!
Incidentally this is also a big part of what motivated Elon to start SpaceX. He was looking at NASA's future plans for human spaceflight and they were basically nonexistent. So he wanted to launch a greenhouse to Mars and stream it growing, to inspire people and hopefully get things moving in the right direction again. NASA wasn't interested in any such things, the Russians wanted too much $$$, and so SpaceX was born.
